A simple model of giant magneto-impedance effect in amorphous thin films
Creators
Description
A simple model of giant magneto-impedance (GMI) effect in amorphous thin films is proposed and the expressions of effective permeability and impedance are derived in the frame of classical electrodynamics and ferromagnetism. The dependence of GMI effect on the external magnetostatic field and the frequency of alternating current is discussed in the viewpoint of the energy conversion in the film. Numerical simulation is conducted and the calculated GMI effect shows reasonable consistency with that measured on a (CoFe)80B20 amorphous film
