Abstract
We present the evolution of magnetic anisotropy obtained from the magnetization curve of (Fe0.76 Si0.09 B0.10 P0.05)97.5 Nb2.0 Cu0.5 amorphous and nanocrystalline alloy produced by a gas atomization process. The material obtained by this process is a powder exhibiting amorphous character in the as-atomized state. Heat treatment at 480◦ C provokes structural relaxation, while annealing the powder at 530◦ C for 30 and 60 min develops a fine nanocrystalline structure. Magnetic anisotropy distribution is explained by considering dipolar effects and the modified random anisotropy model.
