The temperature dependence of the integrated intensity of optical magnon sidebands and the differential extinction coefficient of inelastic light scattering in two-sublattice antiferromagnets with spin X = 1 are calculated. The zeroth approximation of the self-consistent-field method (SCFM) with exact allowance of the single-ion anisotropy is considered. The theory is applied to some antiferrornagnets with Ni ions. The agreement of theoretical and experimental results is satisfactory.Die Temperaturabhkngigkeit der integralen Intensitat der Magnon-Seitenbander und des differentiellen Extinktionskoeffizienten der inelastischen Lichtstreuung werden in ZweiUntergitter-Antiferromagnetika mit Spin S = 1 berechnet. Die nullte Naherung der ,,selfconsistent-field"-Methode (SCFM) wird bei exakter Berucksichtigung der Ein-IonenAnisotropie betrachtet. Die Theorie wird auf Antiferromagnetika mit Ni-Ionen angewendet. Die Ubereinstimmung zwischen theoretischen und experimentellen Ergebnissen ist befriedigend.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
