Abstract :
The effective magnetic anisotropy Keff of Fe87-x Cu1Nb3SixB9 nanocrystalline alloys was studied by means of the law of approach to saturation. The results show that the effective magnetic anisotropy K eff decreases with the increasing Si content of the alloys. It results from a decrease in the magnetocrystalline anisotropy K1 of the α-Fe(Si) phase in the alloys, and the variation of the effective magnetic anisotropy Keff with the magnetocrystalline anisotropy K1 is linear. The technical magnetic properties are improved by increasing the Si content of the nanocrystalline alloys
