摘要：

The dependences of the magnetoimpedance ratio DeltaZ/Z of soft magnetic Co67Fe3.85Ni1.45B11.5Si14.5Mo1.7 glass-coated amorphous microwires with various geometric ratio p upon axial magnetic field H has been measured for the frequency f range 0.06-15 MHz, driving current amplitude I of 0.75-2 mA, and H up to 2400 A/m. Surface hysteresis loops have been measured by transverse magnetooptical Kerr effect (MOKE). A maximum relative change in the giant magnetoimpedance (GMI) ratio DeltaZ/Z up to around 615% is observed at f = 10 MHz and I = 0.75 mA in the sample with rho approximate to 0.98. Application of de bias current strongly affects the GMI ratio. A maximum of GMI ratio occurs approximately at the same field as the coercivity of surface loops.
