Descripción
Sumario: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.
