Предметные рубрики: BIQUADRATIC EXCHANGE LATTICE Ключевые слова (''Своб.индексиров.''): s-d(f) exchange model--mult i-site spin-spin interactions Аннотация: Using the diagram technique for Matsubara Green's functions it is shown that the dynamics of the localized spin subsystem in the s-d(f) model can be described in terms of an effective spin model with multi-site spin-spin interactions. An exact representation of the action for the effective purely spin model is derived as an infinite series in powers of s-d(f) exchange interaction J. The indirect interactions of the 2nd, 3rd and 4th order are discussed.
