Magnetic and Random Anisotropy Studies in some Amorphous Fe-Based Compounds

Abstract

We have studied the magnetization of melt spun amorphous Fe_100-x-yCr_x(PCSi)_y alloys with 4 ≤ x ≤ 11 and 19 ≤ y ≤ 22 under magnetic fields up to 18 kOe, and have analyzed the results at 10 K in the framework of the phenomenological model of Chudnovsky and Serota. Behaviour of magnetic moment and exchange and anisotropy constants has been compared to that of the same parameters in amorphous FeNi(BSi), FeNiCr(BSi) and FeV(BSi).
