Abstract:
Quasiparticle excitations provide viable information on the physics of unconventional superconductors. Higgs and Leggett modes are some of the classic examples. Another important bosonic excitation is the spin exciton originating from the sign-changing superconducting gap structure. Here we report a direct observation of the temperature-dependent spin exciton in the Andreev spectra of iron-based superconductors. Combined with the other experimental evidence, our observation confirms the extended s-wave (s±) order parameter symmetry and indirectly proves the spin-fluctuation mechanism of Cooper pairing.

Abstract:
AbstractA spin-1/2 Heisenberg antiferromagnetic chain is one of the most important paradigmatic models in quantum magnetism. Its ground state is a spin singlet, while the excitation spectrum is formed by gapless fractional excitations, spinons. The presence of alternating g-tensors and/or the staggered Dzyaloshinskii-Moriya interaction results in opening the energy gap $$\varDelta \propto H^{2/3}$$ Δ ∝ H 2 / 3 , once the magnetic field H is applied. A fairly good understanding of this phenomenon was achieved in the framework of the sine-Gordon quantum-field theory, taking into account the effective transverse staggered field induced by the applied uniform field. The theory predicts solitons and antisolitons as elementary excitations, as well as their bound states, breathers. Here, I review recent high-field electron spin resonance spectroscopy studies of such systems, focusing on peculiarities of their spin dynamics in the sine-Gordon regime and beyond.

Abstract:
We report on the resonant excitation of spin waves in micro-structured magnetic thin films by short-wavelength surface acoustic waves (SAWs). The spin waves as well as the acoustic waves are studied by micro-focused Brillouin light scattering spectroscopy. At low magnetic bias fields, a resonant phonon–magnon conversion is possible, which results in the excitation of short-wavelength spin waves. Using micromagnetic simulations, we verify that during this excitation both energy and linear momentum are conserved and fully transferred from the SAW to the spin wave. This conversion can already be detected after an interaction length of a few micrometers. Thus, our findings pave the way for miniaturized magneto-elastic spin-wave emitters for magnon computing.

Abstract:
Ultracold atoms confined to periodic potentials have proven to be a powerful tool for quantum simulation of complex many-body systems. We confine fermions to one dimension to realize the Tomonaga-Luttinger liquid model, which describes the highly collective nature of their low-energy excitations. We use Bragg spectroscopy to directly excite either the spin or charge waves for various strengths of repulsive interaction. We observe that the velocity of the spin and charge excitations shift in opposite directions with increasing interaction, a hallmark of spin-charge separation. The excitation spectra are in quantitative agreement with the exact solution of the Yang-Gaudin model and the Tomonaga-Luttinger liquid theory. Furthermore, we identify effects of nonlinear corrections to this theory that arise from band curvature and back-scattering.

Abstract:
Spin-flip excitations in non-doped Cd 0.93 Zn 0.07 Te/Cd 0.48 Zn 0.04 Mn 0.48 Te quantum wells have been comprehensively studied by spin-flip Raman scattering (SFRS) spectroscopy and time-resolved Kerr rotation (TRKR) spectroscopy. In 4 nm quantum well, two spin-flip Raman peaks were observed in addition to the multiple Mn 2+ spin-flip scatterings. The spin-flip energies are isotropic against the magnetic field direction and well described by modified Brillouin functions. Based on the circumstantial analysis, they are assigned to the spin-flip of residual electrons and the electron spin-flip in the localized exciton, respectively, even though the large energy difference between the two electron spin-flip processes is a puzzle. While, in 9 nm quantum well a strange spin-flip excitation was observed together with a very weak Mn 2+ spin-flip scattering. The spin-flip energy changed strangely up to the magnetic field 4T, and then linearly increased with field (| g *|=1.15). A high-resolution TRKR spectroscopy revealed an unusual temperature dependence, which resembled "softening mode" of spin resonance observed in p-doped ferromagnetic CdMnTe quantum wells. However, these behaviors are well understood by an "inverted spin configuration", which results from a negative g*-factor and a very weak s-d interaction between the electrons and the manganese ions in the barrier.

Spin-polarized electron energy loss spectroscopy (SPEELS) probes the spin-dependent electron-hole pair excitation spectrum at surfaces. It is a very surface sensitive method for the detection of surface magnetization. Indirectly, information on surface magnetic moments is obtained.

Full text
Abstract:
Shaped pulses can be used for uniform spin-1 excitation. The effects of the pulses on spin-1 excitation is seen as distortion of two types: phase distortions and amplitude distortions. By reducing the distortions a spin-1 excitation becomes more uniform. In the case of time-symmetric shaped pulses, spin-1 excitation is free of phase distortions. The spin-1 excitation in that case can be made uniform over a larger frequency bandwidth. The number of possible shaped pulses is so large that a computer-aided search is needed to find the desirable shaped pulses. A theoretical analysis is used to find the connection between a shaped pulse and the corresponding spin-1 excitation. The theoretical analysis in density matrix formalism gives the spin-1 excitation in closed-form expressions that are too complicated. In such a case the connection between a shpaed pulse and spin-1 excitation is not straightforward. A brute-force search for a desirable shaped pulse can consume too much computer time and thus time the scope of the search. By using the formalism of quaternions in the theoretical analysis, spin-1 excitation is presented in simple closed form expressions. It is then shown tht if the choice is limited to time-symmetric shaped pulses then these closed form expressions become much simpler. It is also shown that a spin-1 excitation is free of phase distortions in that case. These simple closed form expressions can be used as the building blocks of a much more concise program code for the computer aided search. As a result a computer aided search for a desirable shaped pulse becomes much faster in speed and larger in scope. More shaped pulses for improved spin-1 can be found.

Abstract:
Le sujet principal de cette thèse est l'étude de métallocènes déposés sur une surface de cuivre. Leurs adsorptions et propriétés électroniques sont expérimentalement étudiées par microscopie à effet tunnel (STM) et spectroscopie par effet tunnel (STS). Nos résultats ont été validés par des calculs se basant sur la théorie de la fonctionnelle de la densité (DFT). Plus précisément, nous avons étudié la façon dont le ferrocène FeC10H10 et le nickelocène NiC10H10s'adsorbent sur le cuivre. Nous avons découvert que ces métallocènes forment spontanément des réseaux alternant molécules horizontales et verticales. Nous avons ensuite modifié la structure du ferrocène par l'ajout d'un atome de cobalt et caractérisé les propriétés magnétiques de la nouvelle molécule ainsi créée, notamment l'apparition d'un effet Kondo témoignant de l'apparition de propriétés magnétiques au sein de la molécule. L'étude spectroscopique du nickelocène a révélé une excitation de la molécule à basse énergie.Cette excitation se traduit par une réorientation du moment de spin de la molécule, passant d'une orientation perpendiculaire à l'axe principal de la molécule à une orientation parallèle à cet axe.Nous avons finalement transféré un nickelocène sur la pointe STM et utilisé cette pointe moléculaire pour sonder les états d'une seconde molécule. Nous avons alors obtenu une double excitation de spin dans notre jonction tunnel, avec une augmentation significative de la conductance due aux excitations
The main subject of this PhD thesis is the study of metallocenes deposited on copper surfaces. Their adsorptions and electronic properties are experimentally studied by scanning tunnelling microscopy(STM) and scanning tunnelling spectroscopy (STS). Our results were confirmed by density functional theory (DFT) computations. More precisely, we studied how ferrocene FeC10H10 and nickelocene NiC10H10 are adsorbed on copper. We found that these metallocenes spontaneously create networks alternating horizontal and vertical molecules. We added a cobalt atom to the ferrocene in order to modify its structure and we characterized the magnetic properties of the new molecule we created, in particular the appearance of a Kondo effect showing that magnetic properties appeared in the molecule. The spectroscopic study of nickelocene revealed an excitation of the molecule at low bias. This excitation consist in a change in the spin orientation of the molecule, going from an orientation perpendicular to the main molecule axis to an orientation parallel to this axis. We finally transferred a nickelocene to the STM tip and used this molecular tip to probe the states of a second molecule. We consequently obtained a double spin excitation in our tunnel junction, with a significant increase of the conductance due to excitations

Abstract:
Ce mémoire est une contribution à l'étude, par spectroscopie optique ultra-rapide, des phénomènes de cohérence optique et de spin relatifs aux états de polaritons de microcavité. Nous réalisons le contrôle cohérent temporel du spin et de la population polaritonique et nous montrons que l'efficacité des processus de diffusion susceptibles de détruire la cohérence optique est affaiblie lorsque la particule présente un caractère photon marqué. A faible densité, l'analyse des cohérences de spin fait apparaître un blocage de la relaxation du spin et de l'alignement du polariton à désaccord négatif. A plus forte densité, un mécanisme d'émission fortement non-linéaire est observé en régime de couplage fort. Cet effet est interprété en terme de luminescence paramétrique stimulée, processus cohérent qui repose sur une approche bosonique des polaritons en interaction via l'échange. Sous champ magnétique transverse, des battements quantiques de spin sont observés. Sous excitation résonante, une corrélation de spin électron-trou au sein de la composante exciton du polariton est mise en évidence. Enfin, nous montrons que la valeur du module du facteur de Landé effectif transverse de l'électron au sein du polariton est d'autant plus forte que la quasi-particule présente un caractère exciton marqué
This thesis is a contribution to the study, via ultrafast time-resolved optical spectroscopy, of optical and spin coherence phenomena involving polaritons in semiconductor microcavities. Coherent control of spin and population of polaritons is performed and we show that the scattering processes responsible for the loss of optical coherence are less efficient when the quasi-particule exhibits a strong photonic character. At low density, the analysis of spin coherences evidences a quenching of spin and alignment relaxation processes for negative detuning. At higher density, a strong non-linear mechanism is observed in the strong coupling regime. This effect is interpreted as stimulated parametric scattering, a coherent process which relies on a bosonic approach of interacting polaritons. Under transverse magnetic field, spin quantum beats are observed. Under resonant excitation, an electron-hole spin correlation is evidenced. To finish with, we show that the absolute value of the effective transverse electron Landé factor increases with the excitonic character of the quasi-particule

Cette thèse se focalise sur le magnétisme à l'échelle atomique grâce au microscope à effet tunnel (STM). Nous étudions des métallocènes, le nickelocène [Ni(C5H5)2], qui présente une signature spectroscopique due à son excitation de spin et le cobaltocène [Co(C5H5)2] qui possède une résonance Kondo. Ces molécules protègent les propriétés magnétiques du métal, si celui-ci est adsorbé sur la surface ou la pointe de notre STM. En plus de la signature caractéristique du nickelocène, nous sommes capables d'étudier les vibrations de ce système lorsqu'il est placé dans un réseau de molécules et en les dopants avec des atomes. Dans ce cas, nous avons pu identifier l'excitation de spin, vibrationnel, ainsi que l'excitation de spin assistée par un vibron. Il en va de même pour le cobaltocène adsorbé sur la pointe, où, certains électrons excitent l'effet Kondo et les modes de vibrations propres de la molécule. De plus, la signature magnétiques de ces molécules sur la pointe, nous permet de créer un champ d'échange avec des objets en surface, nous permettant d'utiliser ces métallocènes comme sonde magnétique et même d'obtenir des images à contraste magnétique pour le nickelocène
This thesis focus on the magnetism at the atomic scale using a scanning tunneling microscope (STM). We study metallocenes, the nickelocene [Ni(C5H5)2], which present a spectroscopic signature due its spin excitation and the cobaltocene [Co(C5H5)2] which possess a Kondo resonance. These molecules protect the magnetic properties of their metal if it is adsorbed on a surface or at the apex of our STM tip. In addition to the characteristic signature of the nickelocene, we can study the vibration of this system when placed into a layer of these molecules doped with atoms. In this case, we could identify the spin and vibrational excitations as well as the vibron-assisted spin excitation. The same applies to the cobaltocene adsorb on the STM tip, since, some inelastic electrons can excite the Kondo resonance and the vibrational modes of the molecule. Furthermore, the magnetic signature of these molecules on the tip can create an exchange field with objects on the surface, allowing us to use the metallocene as magnetic probes and even to obtain images with a magnetic contrast using the nickelocene

L’étude présentée dans ce manuscrit s’inscrit dans le domaine du magnétisme de surface, qui a connu de grands développements ces dernières années grâce au microscope à effet tunnel (STM). Elle a pour but de montrer qu’une molécule simple, le nickelocène [Ni(C5H5)2], peut être attachée au sommet d’une pointe STM afin de produire une pointe-sonde magnétique, qui, dans le cadre de l’imagerie magnétique, présente des avantages indéniables comparés à des pointes conventionnelles. À la différence d’autres systèmes moléculaires étudiés avec le STM, nous montrons que les propriétés magnétiques du nickelocène en phase gazeuse sont préservées en présence d’un métal, même lorsque la molécule est attachée au sommet d’une pointe STM. Nous présentons trois résultats marquants avec cette pointe-sonde moléculaire: 1) Nous montrons que l’on peut contrôler le spin du nickelocène, activant à souhait un effet Kondo ; 2) Nous produisons à l’aide du courant tunnel des excitations entre les états de spin du nickelocène, que nous pouvons aisément identifier au travers de la conductance moléculaire. Ces états sont sensibles à toute perturbation magnétique extérieure au nickelocène; 3) Au travers de ces excitations, nous sondons alors le magnétisme de surface. Nous montrons qu’en couplant magnétiquement la pointe-sonde moléculaire avec des atomes, soit isolés soit dans une surface ferromagnétique, nous pouvons mesurer leur polarisation de spin, ainsi que le couplage d’échange nickelocène-atome. Ce dernier permet d’obtenir un contraste magnétique en imagerie STM à l’échelle atomique
The study presented in this manuscript is part of the field of surface magnetism, which has undergone major developments in recent years thanks to the scanning tunneling microscope (STM). It aims to show that a single molecule, nickelocene [Ni(C5H5)2], can be attached to the tip of a STM to produce a magnetic probe-tip, which, in the context of magnetic imaging, has undeniable advantages compared to conventional tips. Unlike other molecular systems studied with STM, we show that the magnetic properties of nickelocene in the gas phase are preserved in the presence of a metal, even when the molecule is attached to the tip of a STM. We present three remarkable results with this molecular probe-tip: 1) We show that we can control the spin of nickelocene, activating at will a Kondo effect; 2) We monitor the spin states of nickelocene by producing electrically-driven excitations, which we can easily identify through the molecular conductance. These states are sensitive to the magnetic environment surrounding nickelocene; 3) We use these states to probe surface magnetism. We show that by magnetically coupling the molecular probe tip with single atoms, either isolated or in a ferromagnetic surface, we can measure their spin polarization, as well as the nickelocene-atom exchange coupling. By monitoring this coupling it is possible to obtain a magnetic contrast in the STM images with atomic-scale resolution

Abstract:
La structure sous-jacente dans la zone A~100, N~60 a été étudié intensivement et extensivement, principalement par décroissance β et spectroscopie γ suite à des réactions de fission. Autour de N~60, en ajoutant juste quelques neutrons, protons un changement de forme rapide des états fondamentaux se produit, allant de sphérique à bien déformé. La coexistence de forme observée dans les noyaux de Sr et Zr est supposée avoir lieu dans toute la région. Les mécanismes impliqués dans l'apparition de la déformation n'étaient pas clairement identifiés. L'interaction entre les orbitales de Nilsson montantes et descendante est évoqué comme l'une des principales raisons du changement de forme. Cependant, une identification claire des orbitales proton et neutron en jeu était nécessaire. A cet effet, l'étude des isotopes ⁹³′⁹⁵′⁹⁷′⁹⁹Rb riches en neutrons a été réalisé excitation Coulombienne au CERN (ISOLDE) en utilisant le post-accélérateur REX-ISOLDE et le dispositif Miniball. Les structures excitées encore inconnues des isotopes ⁹⁷′⁹⁹Rb ont été peuplées et observées. Les coïncidences de transitions γ des états de basse énergie ont été observées et leur corrélations ont permis la construction de schémas de niveaux. Les probabilités de transitions associées ont été extraites grâce code GOSIA. Les éléments de matrice de l'opérateur électromagnétique observées constituent de nouveaux apports afin d'effectuer de nouveaux calculs théoriques permettant de statuer sur les orbitales impliquées. La sensibilité des expériences de ce type peut être accrue en utilisant des faisceaux radioactifs d'ions dont le spin nucléaire est polarisé. La technique de polarisation des feuilles orientées (TFT) fut étudiée dans ce but au CERN. Un nouveau polariseur TFT et un dispositif β-NMR ont être créés et installés après REX-ISOLDE. La connaissance du processus de polarisation associé à la technique reste incomplète à ce jour et de plus amples études sont nécessaires. Des tests préliminaires prometteurs ont été effectués sur le noyau de ⁸Li afin de déterminer le potentiel du dispositif actuel.

Abstract:
Cette thèse est consacrée à l'étude des effets du couplage spin-orbite dans des puits quantiques semi-conducteurs dopés (GaAs et CdMnTe), par spectroscopie Raman électronique. Dans ces structures existent des champs magnétiques intrinsèques (Dresselhaus et Rashba). Ces champs offrent des moyens attractifs pour manipuler le spin des électrons, mais contribuent aussi à la relaxation de spin via leur dépendance avec le vecteur d'onde de l'électron (mécanisme D'yakonov-Perel'). Nous montrons que pour les modes collectifs de spin de puits quantiques, le scénario destructif D'yakonov-Perel' est transformé en un scénario constructif : les interactions Coulombiennes font émerger un champ spin-orbite collectif, proportionnel au vecteur d'onde de l'excitation, et renforcé d'un facteur de plusieurs unités par rapport aux champs spin-orbite individuels. Nous mettons d'abord en évidence ces effets spin-orbite géants sur le plasmon de spin inter-sous-bande, dans des puits quantiques de GaAs. Le champ spin-orbite collectif, qui conduit à un éclatement de structure fine du spectre plasmon, est superposé à un champ magnétique extérieur et cartographié dans l'espace réciproque. Nous étudions ensuite l'onde de spin intra-sous-bande du gaz d'électrons polarisé en spin, dans des puits quantiques magnétiques dilués de CdMnTe. Le champ spin-orbite collectif se superpose ici au champ Zeeman géant du composé. Nous mesurons le facteur de renforcement du champ spin-orbite collectif. Enfin, nous déterminons la dépendance du facteur de renforcement avec la densité électronique, et démontrons la possibilité de contrôler l'amplitude du champ spin-orbite collectif à l'aide d'une grille optique.

The formal theory is presented, and used to show how neutron scattering measurements give direct access to a variety of correlation and response functions which characterize the equilibrium properties of bulk matter. The determination of atomic arrangements and magnetic structures by neutron diffraction and neutron optical methods is described, including single-crystal and powder diffraction, diffuse scattering from disordered structures, total scattering, small-angle scattering, reflectometry, and imaging. The principles behind the main neutron spectroscopic techniques are explained, including continuous and time-of-flight inelastic scattering, quasielastic scattering, spin-echo spectroscopy, and Compton scattering. The scattering cross-sections for atomic vibrations in solids, diffusive motion in atomic and molecular fluids, and single-atom and cooperative magnetic excitations are calculated. A detailed account of neutron polarization analysis is given, together with examples of how polarized neutrons can be exploited to obtain information about structural and magnetic correlations which cannot be obtained by other methods. Alongside the theoretical aspects, the book also describes the essential practical information needed to perform experiments and to analyse and interpret the data. Exercises are included at the end of each chapter to consolidate and enhance understanding of the material, and a summary of relevant results from mathematics, quantum mechanics, and linear response theory, is given in the appendices.
