Radiation damage and the magnetic domain structure of amorphous GdCo thin films

Abstract

Describes electron microscope observations of the effect of ion irradiation on the magnetic domain structure of amorphous thin films in GdCo. The results support in principle the previous findings of Gambino et al. (1974) that uniaxial anisotropy in these materials can be destroyed by displacement damage although it is found that heavier doses are required than those used by Gambino et al.
