Abstract:
In this paper, a three dimensional model for the giant magneto-impedance (GMI) effect in thin film structures is developed using the finite element method(FEM) with a GMI permeability model embedded. One-layer, three-layer, and five-layer thin film structures are simulated. The GMI effect and the sensitivity are calculated as a function of the external magnetic field, driving frequency, and the thickness of the magnetic layers. The results show that the five-layer structure has the best performance, which is in accordance with experimental results. The GMI ratio and the sensitivity first improve with the increasing thickness of the magnetic layer but reach saturation at a certain value of the thickness. In a five-layer structure,saturation of the GMI effect becomes effective at about 3 μm thickness of the magnetic layers, where a GMI ratio of 1125% was obtained, with a corresponding sensitivity of 0.37%/A/m (29.6%/Oe).
