• We present a review of the giant magneto-impedance (GMI) in Co-rich amorphous wires and films, in which effects with sensitivity up to 100 and 8%/Oe, respectively, have been reported even for tiny samples. GMI, a side-effect of the skin effect, depends considerably upon the particular magnetic structure and frequency range. Considering the different magnetic anisotropies (circumferential or helical in a wire, and transverse in a film), various types of GMI characteristics can be obtained: having a maximum or minimum at zero external field, without a hysteresis or exhibiting a sharp bistable hysteresis, symmetrical or asymmetrical with respect to the field. This suggests great technological potential of GMI in a wide range of sensor applications.
