Abstract:
The magnetoimpedance of a film trilayer consisting of magnetically soft and magnetically hard films separated by a high-conductivity nonmagnetic spacer is theoretically investigated. A model for describing the dependences of the sample impedance on the external magnetic field and frequency is proposed, which is based on simultaneous solution of the linearized Maxwell and Landau–Lifshitz equations and takes into account the magnetostatic interaction between the magnetic layers. It is demonstrated that the magnetostatic interaction changes the distribution of magnetization of the magnetically soft film and leads to the occurrence of asymmetry in the field dependence of the impedance. The results obtained can be used in the development of weak magnetic field sensors.
