Description
Summary:We present the evolution of magnetic anisotropy obtained from the magnetization curve of (Fe<sub>0.76</sub>Si<sub>0.09</sub>B<sub>0.10</sub>P<sub>0.05</sub>)<sub>97.5</sub>Nb<sub>2.0</sub>Cu<sub>0.5</sub> 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.
