Resumen

We present the evolution of magnetic anisotropy obtained from the magnetization curve of (Fe_0.76 Si_0.09 B_0.10 P_0.05)_97.5 Nb_2.0 Cu_0.5 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.
