Abstract

We have studied the magnetization of melt-spun amorphous Fe_80-y-xNi_yMn_xB₁₂Si₈ alloys with 20 ≤ y(Ni) ≤ 50 and 0 ≤ x(Mn) ≤ 2 under magnetic fields up to 18 kOe, and have analyzed the results at 4.2 K, based on the random magnetic anisotropy (RMA) model. The approach to saturation is established in the form of H^-1/2 for the various samples. The exchange constant A and the ferromagnetic correlation length R_f decrease with Mn addition while the local random anisotropy is enhanced.
