Temperature dependence of the magneto-impedance effect in Co-rich amorphous glass-covered wires

Results on the temperature dependence of the magneto-impedance response of Co68.15Fe4.35Si12.5B15 amorphous glass-covered wires between room and Curie temperatures are reported for the first time. The largest response is obtained at room temperature, the magnitude of the effect decreasing with the increase of temperature. An increase of the magneto-impedance response is observed just below the Curie point
