Spin}orbit induced magnetic phenomena in bulk metals and their surfaces and interfaces
Ruqian Wu,Arthur J Freeman +1 more
TL;DR: In this article, the theoretical/computational treatment of the weak spin-orbit coupling in magnetic transition metals and their alloys and its important physical consequences are discussed, such as magneto-crystalline anisotropic anisotropy, magnetostriction, magnetooptical Kerr effects and X-ray magnetic circular dichroism.

Spin-phonon coupling in antiferromagnetic nickel oxide
Ece Aytan,Bishwajit Debnath,Fariborz Kargar,Yafis Barlas,M. M. Lacerda,M. M. Lacerda,Junxue Li,Roger K. Lake,Jing Shi,Alexander A. Balandin +9 more
TL;DR: In this article, the spin-phonon coupling coefficients in NiO were determined using ultraviolet Raman spectroscopy of NiO, and it was shown that the spins of Ni atoms interact more strongly with the longitudinal than transverse optical phonons and produce opposite effects on the phonon energies.

Spin - Phonon Coupling in Nickel Oxide Determined from Ultraviolet Raman Spectroscopy
Ece Aytan,Bishwajit Debnath,Fariborz Kargar,Yafis Barlas,M. M. Lacerda,Junxue Li,Roger K. Lake,Jing Shi,Alexander A. Balandin +8 more
TL;DR: In this article, the spin-photon coupling coefficients in NiO were obtained by using ultraviolet (UV) Raman spectroscopy, and it was shown that the spins of Ni atoms interact more strongly with the longitudinal optical phonons than with the transverse optical (TO) phonons, and produce opposite effects on the phonon energies.

Effects of Configuration Interaction on Intensities and Phase Shifts
TL;DR: In this paper, a theoretical analysis of the shape of the 2s2p^{1}P resonance of He observed in the inelastic scattering of electrons is presented. But the analysis is restricted to the case of one discrete level with two or more continua and of a set of discrete levels with one continuum.

Magnetic Structures of MnO, FeO, CoO, and NiO
TL;DR: In this paper, the antiferromagnetic arrangement of moments in MnO, FeO, CoO, and NiO have been investigated by powder neutron diffraction and the results for the four oxides are consistent with a structure in which the magnetic moments are arrayed in ferromagnetic sheets parallel to (111) planes, and the direction of magnetization in neighboring planes is antiparallel.
