Abstract :
A new method of measuring magnetic anisotropy dispersion using a biaxial VSM was presented. This method made it possible to measure the magnitude and angular dispersion of magnetic anisotropy independently and quantitatively by measuring a reversal of magnetization perpendicular to a magnetic field. Adopting the measured anisotropy dispersion, the frequency dependence of the permeability for soft magnetic thin films has been calculated
