A computer simulation study on a two-sublattice magnetic system

Abstract We report on the magnetization, its first- and second-field derivatives, and torque on a PrCo5 single crystal using the two-sublattice model in the mean field approximation. The anisotropy energy of the compound is described by first- and second-order anisotropy constants of the Co and Pr sublattices. The structure of the magnetization, its field derivatives and torque fairly supports the working of this model. Comparison with the magnetization behavior, however, in the absence of canting shows some variance with the two-sublattice model especially as the magnetic saturation is approached.
