The Influence of the Magnetic Susceptibility of Coated Amorphous Ribbons on Giant-Magneto Impedance Effect

Abstract

Different inorganic thin layers (based on Cobalt, Copper and Nickel complexes) were grown on the surface of Co-rich Fe5.85Co70.15Mo4B15Si5 (Metglas 2705X) amorphous ribbons by a chemical coating process to improve the giant magneto impedance (GMI) effect. Magnetic susceptibilities of the inorganic complexes were measured by the Gouy's method. Therefore, the influence of the magnetic susceptibility of thin layers, which are coated on the surfaces of the amorphous ribbons, on the GMI effect has been studied. Cobalt, copper and nickel complexes were found to be diamagnetic, paramagnetic and paramagnetic, respectively. The results showed that changes in the GMI effect are related to the magnetic susceptibility.
