Abstract:

Spin-glass effects have been observed in copper-nickel-iron paramagnetic alloys with a nickel concentration of 20−30 at.% and an iron concentration of 0.6−1.4 at.%. It was determined that a disordered ferromagnetic phase appears in copper-nickel-iron alloys as the percolation threshold is approached.

Abstract:

SQUID magnetometer characterization of Ca–Ni–K–O catalyst materials reveals complex magnetic behavior. The magnetic properties are generally determined by the antiferromagnetic material NiO, but samples with traces of elemental nickel show marked effects of ferromagnetism. Potassium doping enhances the formation of metallic nickel. Further deviations from bulk NiO properties can be attributed to NiO particle size effects (superparamagnetism) and to the presence of paramagnetic impurities, possibly Ni3+ ions.

The ligand precursors were thoroughly characterized using NMR spectroscopy, ESI-MS, and IR spectroscopy. The metal complexes were thoroughly characterized using single crystal X-ray diffraction, elemental analysis, ESI-MS, and cyclic voltammetry.

Abstract:

Glasses in the NiO–TiO2 system in the composition range 15 to 25 mol% of NiO have been synthesized by the sol-gel technique by heat treatment of the precursor sol at 500°C. The glass structure is built up by crosslinking of two units, namely TiO6 octahedron and NiO3 triangle. Glassy structure is confirmed at a microscopic level by scanning electron microscopy. An increase in the values of peak-to-peak width of electron paramagnetic resonance with increasing concentration of Ni2+ is attributed to an enhanced interaction between neighboring paramagnetic Ni2+ ions.

Abstract:

The energy loss (EL) of 5.486 MeV α-particles in ferromagnetic nickel foils was measured at different temperatures of the foils. The temperature of the foils was controlled and recorded using a PC-based temperature controller with an accuracy of ±0.01°C. It is observed that the energy loss in ferromagnetic nickel increases by 2–5% as the material goes from ferromagnetic to paramagnetic state. Thus our results show that the phase transition in ferromagnetic materials affects energy loss.

Reliable data on the temperature dependence of thermodynamic properties of alloy phases are very useful for modeling the behavior of high-temperature materials such as nickel-based superalloys.

Abstract:

Electron paramagnetic resonance (EPR) spectra of synthetic diamond microcrystals with NV(-) centers have been studied. It is shown that under the conditions of irradiation of the material with the light of a xenon lamp at low temperatures ~100 K, the intensities of the EPR signals corresponding to the “forbidden” (dms=2) and low-field allowed (dms=1) transitions are amplified several times, while the EPR signals from paramagnetic nitrogen and impurity nickel in the charge state -1 practically do not change. This is due to a change in the population of levels of the ground triplet state of the

Abstract:

The complex [1,2-bis(di-tert-butylphosphanyl)ethane-κ2P,P′]diiodidonickel(II), [NiI2(C18H40P2] or (dtbpe-κ2P)NiI2, [dtbpe is 1,2-bis(di-tert-butylphosphanyl)ethane], is bright blue–green in the solid state and in solution, but, contrary to the structure predicted for a blue or green nickel(II) bis(phosphine) complex, it is found to be close to square planar in the solid state. The solution structure is deduced to be similar, because the optical spectra measured in solution and in the solid state contain similar absorptions. In solution at room temperature, no31P{1H} NMR resonance is observed,

Abstract:

The bond length, average binding energy, magnetic moment per atom and the ionic potential of Nin(2-13) clusters were calculated in detail. The variations of magnetic moment per atom and the ionic potential agree well with experimental data. Theoretical results show that BPW91/Lanl2dz method is the best method and basis set for nickel clusters research, respectively. The ground state configurations and electronic structure properties of Nin(2-13) clusters were investigated using the BPW91/LanL2DZ level of DFT method. Through the molecular orbital, we could explain the paramagnetic and diamagnet

Abstract:

In this paper, we have shown how the presence of pores and pore morphology influence on magnetic phase transition temperatures in mesoporous ferromagnetic materials. Model calculations have demonstrated the possibility to obtain macroscopic mesoporous samples with notably reduced Curie temperatures which is also further depressed in the case the pore morphology is more complicated. The results have been obtained on the basis of the experimentally verified correlation between the Curie temperature and cohesive energy of the material and illustrated using the examples of pure mesoporous iron, ni

Abstract:

This article shows a study of the effect of mechanical activation of the initial mixture of reagents NiO and Fe2O3 at different speeds of grinding bowl rotation on synthesis of nickel ferrite. Nickel ferrite was produced by the solid-phase synthesis at a temperature of 900 °C for 240 minutes. The obtained ferrite samples were investigated by thermal gravimetric and X-ray phase analysis. The Curie temperature values are obtained, as well as the magnitude of the change of detected instrument weight at the magnetic phase transition (ferromagnetic-paramagnetic) of nickel ferrite using thermal grav
