Spin structures in the presence of an external magnetic field have been studied for the two-sublattice model. The field dependence of the spin configurations has been found to depend sensitively on the competition among the exchange and the anisotropies of the two sublattices. Four kinds of magnetization processes have been identified in the ferrimagnetic case, including first-order moment reorientations (FOMRs), taking only the second-order anisotropies into account. For this case, we present phase diagrams defining ranges of parameter values leading to different magnetization processes. The spin structures and the magnetization processes are also discussed for the two-sublattice model with sixth-order anisotropies. |
