Influence of Magnetic Field Intensity on the Shape of them-T Curves for Fe73.5Cu1Nb3Si13.5B9 Alloy
Influence of Magnetic Field Intensity on the Shape of the μ—T Curves for Fe73.5Cu1Nb3Si13.5B9 Alloy

Under different magnetic field intensities, the dependence of the permeability m on temperature T(m-T curve) for the Fe73.5Cu1Nb3Si13.5B9 alloy annealed at 350~620°C was investigated. The results showed that the magnetic field intensity had a remarkable influence on the shape of m-T curves. For amorphous alloy, the sharp Hopkinson peak of m-T curve disappeared gradually with the increase of magnetic field intensity.
