The temperature dependence of the magneto-impedance effect in the Co-based amorphous wires

Abstract We used CoFeSiB amorphous wires to investigate the influence of heating and tensile stress on the magneto-impedance value. Measurements were performed with as-cast wires without cover of 100 μm diameter and 7 mm length. Experiments were carried out at current frequencies 10, 30 and 50 MHz, in temperature range from 23 to 180 °C.
