Abstract
A spin-reorientational phase transition in the basal plane, which was exper imentally observed earlier, is explained in terms of a model in which the c rystalline Fe-ion matrix is considered as a continuum, while dopant Dy ions are treated as quasi-Ising ions. The transition is established to be due t o the Fe-subsystem anisotropy competing with that of the rare-earth subsyst em. (C) 2000 MAIK "Nauka/ Interperiodica".
