Spin-wave and anisotropy studies in amorphous Fe-Cr-P-C-Si

摘要

Random anisotropy and spin-wave studies on amorphous Fe100-y-zCry(PCSi)(z),(4 less than or equal to (y) less than or equal to 11, 19 less than or equal to (z) less than or equal to 22), have been performed. The behavior, as a function of temperature, of the magnetization, anisotropy and exchange parameters has been studied. The spin-wave stiffness constant and the average mean-square range, < r(2) >, of the exchange interaction have been evaluated, and the results obtained have been discussed.
