Summary:We report the salient features of the magnetic properties of as-quenched and annealed Fe 82(Zr, Hf, Nb) 7B 10Cu 1 alloys. Temperature dependence of magnetization was carried out and magnetic entities were investigated using the spin-wave theory and mean-field theory. Annealed alloys have been shown to exhibit good soft magnetic properties especially in high-frequency range. The presence of a rather high concentration of boron appears to have suppress the growth of BCC-Fe grains and also stabilize the amorphous matrix. Our result reveals that the reason for good soft magnetic properties is associated with the reduction of the magnetic anisotropy by rather strong exchange energy when annealing temperature is increased.
