EN

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, μ_{DR}, as a function of biasing DC field, measured with very small alternative field amplitude, less than 0.05H_c. The domain wall movement component is obtained by the integration of the permeability obtained by extraction of μ_{DR} from the differential permeability derived from one branch of the quasi-static major loop.
