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

Random anisotropy and spin-wave studies on amorphous Fe 100− y− z Cr y (PCSi) z , (4⩽ y⩽11, 19⩽ z⩽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-squ...

Zusammenfassung:	Random anisotropy and spin-wave studies on amorphous Fe 100− y− z Cr y (PCSi) z , (4⩽ y⩽11, 19⩽ z⩽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.
