Abstract
A bicrystal film is modeled as an ensemble of clusters of four particles which interact via short-range exchange coupling. Their easy axes are oriented pairwise along two randomly chosen orthogonal directions and the relaxational dynamics of the resultant clusters are described in terms of a multilevel master equation. The randomly deposited bicrystal film is compared with a randomly deposited film of uniaxial clusters. The relaxational properties of the entire array are determined by the easy axes arrangement and by the nature of coupling within the cluster. In particular, for ferromagnetic coupling the occurrence probability of fully magnetized bicrystal cluster states is high and we propose that in conjunction with the highly isotropic coercivity this property leads to a sharp transition between film regions magnetized in opposite directions.
