MODELING THE FREQUENCY DEPENDENCE OF THE MAGNETOIMPEDANCE EFFECT OF AMORPHOUS RIBBONS BY THE FINITE ELEMENT METHOD

Frequency dependence of the magnetoimpedance effect of amorphous ribbons was studied. Different reasons of the discrepancy in magnitude of theoretically calculated sensitivity and experimental data were considered. A complementary model for variation of magnetic permeability was created.The research was carried out within the state assignment of M.N. Mikheev Institute of Metal Physics of the Ural Branch of the Russian Academy of Sciences of № АААА-А18-118020290129-5 (theme "Magnet")
