Development of Magnetic Microwires with High Magneto-Impedance Effect

Year: 2025

Type: conference-paper

Abstract: Giant Magneto-Impedance (GMI) effect is ideal for developing high-performance magnetic sensors due to its high sensitivity to magnetic fields and the ease of manufacturing magnetic sensors. We provide our attempts to improve the GMI effect and magnetic softness of Co-rich glass-coated magnetic microwires. We studied the GMI effect and magnetic properties of Co-rich glass-coated magnetic microwires with two different diameters. Substantially different frequency dependence of GMI effect is observed in studied microwires. A high GMI ratio of about 625% is observed in thinner Co-rich microwire at about 300 MHz.
