Influence of Electron Correlations on Magnetic Properties in TransitionMetals in View of Degeneration

摘要

Transition from high-spin state to low-spin state is considered in this work. The self -energy in one-loop approximation was calculated. The three — orbital periodic Anderson-Hubbardmodel is used to obtain an initial segment of an optical branch in view of degeneration. Thepossibility of experimental verification of the received result by a method of non-elastic dispersionof slow neutrons is mentioned.
