Abstract

Magnetic properties of nanocrystalline alloys produced by crystallization of Fe-Cu-Nb-Si-B amorphous alloys have been investigated. The best result is obtained at the annealing conditions where the main phase is bcc and it is very important to suppress the formation of Fe-B compounds with large magnetocrystalline anisotropy. Homogeneous and ultrafine grain structure has an important effect to improve the magnetic properties. Conclusively, soft magnetic properties of nanocrystalline alloys are related to various factors such as formed phases, ratio of amorphous phase, intrinsic magnetocrystalline anisotropy and magnetic interaction from grain boundary phase.
