Paper Abstract

The recording domain sizes of amorphous DyFeCo thin films are compared with those of films with addition of Nd element. It is shown that NdDyFeCo films possess smaller domain sizes than DyFeCo films do under the same recording conditions. These results may be explained by the temperature dependence of coercivity of the thin films. The addition of Nd element to DyFeCo films plays a role of increasing the coercivity of thin films at high temperature, which has influence on the recording domain sizes.
