Особенности моделирования коллективных магнитных возбуждений в соединениях переходных металлов

Abstract

The question of applicability for different numerical methods to estimate the basic characteristic of the spin spirals in transition metal-based compounds is investigated. Depending on localization of the magnetic moment (bcc Fe and FeGe systems were taken as the example), methods, which include the spatial summing, were found converging or not. It reveals the significance of delocalized magnetic moment in forming of the collective magnetic excitations in real transition metal-based materials.
