Influence of Electron Correlations on Magnetic Properties in Transition Metals in View of Degeneration
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-Hubbard model is used to obtain an initial segment of an optical branch in view of degeneration. The possibility of experimental verification of the received result by a method of non-elastic dispersion of slow neutrons is mentioned.
