摘要：

The effect of film thickness on magnetic properties of Cu80Co20 granular alloy was studied. It was observed that the susceptibility peak temperature, T-M, strongly increases with the film thickness, t, for t < 100 nm. The long-range nature of this effect points to magnetic dipole interaction as responsible mechanism. This dependence of T-M can be explained within the framework of Dormann's theory of dipolar interaction between magnetic particles. The coercive field has different thickness dependence and it is related to formation of magnetic domain structure of Co particles in the granular alloy. (C) 1999 American Institute of Physics.
