Abstract

AbstractThe 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. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
