Abstract
Abstract The knowledge of the basic phenomena governing the magnetoimpedance (skin-depth effect) allows the use of the impedance spectrum to study the dynamic magnetization processes in magnetic materials. By modeling the frequency dependence of the impedance spectrum, the corresponding permeability spectrum can be obtained, from which it is possible to obtain several important parameters concerning the dynamics of the domain walls, namely: domain wall critical speed, wall mobility, domain wall energy and thickness. In this work the technique is outlined and applied to (1 1 0)[0 0 1]FeSi 3% , a very well-known sharp textured magnetic material. The results compare favorably to those known from the literature.
