摘要：
We present our results on studies of soft magnetic properties and GMI effect in thin microwires at elevated frequencies paying special attention to tailoring the GMI effect and achievement of high GMI ratio (Delta Z/Z), high magnetic field sensitivity (dZ/dH) with low hysteretic behavior. We measured magnetic field dependence of real part, of the longitudinal wire impedance up to frequency, f, 4 GHz in Co-rich microwires. We observed that the GMI magnetic field dependence can be tailored either controlling magnetoelastic anisotropy of as-prepared microwires or by heat treatment.
