Abstract:

An approach to the analysis and interpretation of the spectra of photoinduced circular dichroism (PICD) of semiconductor nanocrystals, in particular quantum dots, based on their comparison with the spectra of magnetic circular dichroism (MCD), is proposed. It was shown that the MCD and PICD spectra have similar features. The values of parameters similar to the known parameters A and B of the MCD spectra characterizing the splitting and mixing of states were determined from the PICD spectra.

Abstract:

Magnetic circular dichroism (MCD) has been detected in YBa2Cu3O7–x films in the visible spectral range from 1.5 to 4.5 V (275–825 nm). The MCD spectrum correlates with the absorption spectrum, and its magnitude attains values up to (1–5)·10−4 T−1 at the extremal points. Superconducting and nonsuperconducting samples display different kinds of dispersion and temperature dependences of MCD. For all the investigated samples, the magnetic field dependence of MCD has the form aH+b right up to 7 T, where the coefficient a depends on the temperature and wavelength at which observations were made, whi

This review of the application of the MCD spectroscopic technique to porphyrinoids aims to illustrate the features and unique information that can be obtained and used in the assignment of the optical absorption spectrum and also the electronic structures of porphyrins and phthalocyanines. By illustrating each of the major and readily available spectral features with simple compounds we hope this review will act to guide new users in formulating the questions that room temperature MCD measurements can answer.

Abstract:

We have measured the magnetic circular dichroism (MCD) of X-ray emission spectra (XES) for gadolinium and terbium in the 4d–4f resonant excitation region. Clear MCD signals in the XES were observed and they dramatically changed as the excitation energy changed. Especially, an extremely large MCD signal appeared with the 8D resonant excitation for gadolinium. Comparison between the MCD for XES and total photoelectron yield (TEY) shows that the XES are very insensitive to the surface state. As a result, the measurement of XES was proved to be a superior technique for estimating the genuine magne

Magnetic circular dichroism (MCD) spectra of spinel ferrites MFe 2 O 4 (M = Co, Mn, Fe, Co and Ni) have been measured by using a photon-helicity-switching method. The method achieves high energy resolution and a low noise-to-signal ratio. The Fe L2,3 absorption spectra of MFe 2 O 4 show a similar spectral profile; on the other hand, the MCD spectra show the characteristic fine structures. These differences are attributed to the variety of 3d electron configuration of Fe ions ( Fe 2+ or Fe 3+) and the local symmetry (tetrahedral or octahedral).

Abstract:

Magnetic circular dichroism (MCD) of core-level absorption spectra (XAS) in the soft X-ray region has been measured for the ferromagnetic Heusler alloys Co 2 TiSn , Co 2 ZrSn , and Co 2 NbSn . The Co 2p → 3d XAS–MCD spectra show an obvious contribution of the orbital angular momentum component to the magnetic moment in these alloys. The ratio between the orbital and the spin magnetic moments derived from the MCD spectra varies by more than a factor of 2 within these alloys. The mechanism of this variation is discussed in comparison with the band structure calculation.

Morphology, structure, magnetic properties and magnetic circular dichroism (MCD) were studied for the FexSy and FexSey nanoparticles (NPs) synthesized with the polyol mediated and the thermal decomposition processes, correspondingly, at different regimes. For all NPs samples, but Fe3S4, MCD was measured for the first time. It has been shown that in the case of sulfides, the character of the MCD spectrum changes as the NPs phase composition transforms from Fe3S4 to FeS with the synthesis temperature increase. At the same time, the shape of the MCD spectrum is almost independent of the NPs phase

Abstract:

The selenium-substituted inactive form of mitochondrial aconitase contains one [3Fe-4Se]1+/0 cluster [Surerus, Kennedy, Beinert and Münck (1989) Proc. Natl. Acad. Sci. U.S.A. 87, 9846-9850]. This cluster was studied in both oxidized and reduced states by magnetic CD (MCD) and EPR spectroscopy. In the MCD spectra, intensity and transition wavelength shifts are observed when compared with the spectra of the native [3Fe-4S]1+/0 cluster. These changes are used to differentiate between the charge-transfer transitions originating from inorganic and cysteinyl sulphur. Using also the data from the EPR

Magnetic circular dichroism (MCD) spectra of La 1-x Sr x CoO 3 have been measured at Co 1s and 2p XAS, La 3d and 2p XAS. The contribution of the orbital moment to the total magnetic moment of Co ions became larger with the Sr composition of the La 1-x Sr x CoO 3 system increasing. There was no polarization of the 4f orbital in La but the 5d orbital in La was polarized by the hybridization between the Co 3d orbital and the La 5d orbital.

Abstract:

Magnetic materials containing transition metals such as Fe, Co, and Ni have attracted considerable interest, in particular for their unique properties, which allow them to be applied to devices for magnetic control of optical communications and magneto-optical data storage. Magnetic control of catalysis and electrocatalysis is also a potential application of magnetic materials. Apparent catalytic activity can be controlled via a magnetohydrodynamic (MHD) effect, which affect mass transport rate in the vicinity of the magnetic material.[1] In addition, enantioselectivity can be given to the sys

The ε-Fe2O3 nanoparticles in borate glasses co-doped with low concentrations of Fe2O3 and Gd2O3 were investigated with two experimental techniques – visible magnetic circular dichroism (MCD) and electron spin resonance (ESR). The most prominent features of the MCD spectra are: non-linear dependence of the spectral maxima intensities on the Gd concentration and strong increase with the temperature decrease. The ESR spectra of these glasses exhibit two features with g = 4.3 due to the diluted Fe3+ ions and 2.0 associated both with Fe3+ ions and with nanoparticles. The integrated spectra intensit

Structural characterization by MS and 1 H NMR spectroscopy confirmed the bridged porphyrin dimer structure. The properties of the dimers were characterized by IR, UV-visible absorption, fluorescence and magnetic circular dichroism (MCD) spectroscopy, and electrochemistry studies. Theoretical calculations were carried out to analyze the electronic structures of porphyrin dimers with a bridging amide-bonded xanthene moiety.

The spectral and temperature dependencies of magnetic circular dichroism (MCD) of these films are studied in the temperature range from 300 K down to 8 K. Measured magneto-optical properties are reported in the spectral range between 300 and 600 nm. In ultrathin garnets at temperatures below 160 K, we found that between 360 and 520 nm, the spectral MCD dependencies were typical of bismuth-substituted

Abstract Magnetic circular dichroism (MCD) spectroscopy for manganite films of various compositions and morphologies has been studied in the range of 1.2–3.7 eV. The primary focus was on the temperature behavior of the MCD spectra, as well as the magnetization and resistivity of the films. The data obtained were analyzed in comparison with magneto-optical spectroscopy of the Kerr rotation (KR) on both single crystal and thin film of manganites. It has been established that the MCD response at 2.3 eV is typical for manganites transitioning into a conducting state. Consequently, it reflects a ch

Abstract:

In this paper, we have investigated electronic absorption, magnetic circular dichroism, fluorescence, and phosphorescence spectra for a protonated form of H 2 TPPS 4( H 4 TPPS 4) and the J-aggregates of H 4 TPPS 4. The J-aggregation induces a large red-shift in the B (Soret) and Q absorption bands, while the phosphorescence peaks of H 4 TPPS 4 and its J-aggregates are almost entirely similar. The large red-shift of the B-band is quantitatively explained by the exciton interactions. Thus, the exciton interactions in the J-aggregates are proposed as a useful approach to decrease the energy split
