| The domain wall movement and magnetization rotations processes are separated experimentally in quasi-static magnetization process of a Finemet type ultrasoft magnetic material. The reversible domain rotations contribution is obtained from the integration of the reversible permeability, μDR, as a function of biasing DC field, measured with very small alternative field amplitude, less than 0.05Hc. The domain wall movement component is obtained by the integration of the permeability obtained by extraction of μDR from the differential permeability derived from one branch of the quasi-static major loop. |
