Abstract

The giant magnetoimpedance (GMI) has been measured in as-quenched (Co_0.94Fe_0.06)_72.5Si_12.5B ₁₅ amorphous wire as a function of DC-biased current, I_b, along sample axis and measuring frequency f. The GMI profile during half a cycle of magnetization for I_b = 0 shows a typical behavior of GMI, that is, single peak for f = 0.1 MHz and symmetric two peaks (or f ≤ 0.5 MHz. Asymmetric GMI profile appears for I_b ≥ 0.85mA in the frequency range between 0.1 and 10 MHz, due to the suppression of wall motion by the induced circular field. The field sensitivity amounted to 170%/Oe for 0.1 MHz with I_b = 3.4mA and 150%/Oe for f ≥ 0.5 MHz with 12.7 mA.
