【Abstract】 The influence of Mo content on the magnetic permeability spectra of Fe 82Nb 7-xMo xB 10Cu 1(x=0,1,3,5)nanocrystalline soft magnetic alloys was studied in the frequency range of 1kHz to 1MHz.Domain wall pinning theory was used to explain.Through the permeability spectra it can be seen that the relaxation frequency increased linearly with Mo content.The relation between μ′ and the amplitude of the applied magnetic field disclosed the reason that Mo substitution caused the increase of pinning field which resulted in the increase of relaxation frequency.更多还原
