Abstract

The effects of electron irradiation on a giant magnetoimpedance (GMI) have been investigated for a Co-based amorphous ribbon. The GMI ratio was used to characterize the samples before and after the electron irradiation. The GMI ratio decreased considerably in the electron irradiated samples and the GMI response showed a strong dependence on the irradiated electron energy and driving frequencies. It was shown that the electron irradiations lead to a substantial modification of the magnetic properties including a permeability.
