Abstract

The system of two ferromagnetic layers characterized by different exchange parameters and indirectly coupled by nonmagnetic spacer has been considered in low temperature region. The spin wave parameter B describing the Bloch's T ^3/2^ law has been calculated as a function of thickness and exchange parameters of constituent layers employing the Green fuction method. It has been shown that anisotropy in the interface region influences the dependence of B on the inverse thickness of the system. (Β© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

For magnetic solids with several unpaired spins per spin site, the average spin orbital interaction energies 1 e2 and the average spin orbital interaction energy squares 1( e) 2 2 were de5ned as a qualitative measure for the strengths of their antiferromagnetic spin exchange interactions. The trends
