If, during the preparation, an external magnetic field as high as 300 O\\\"{e} is applied upon cooling the material is named field-cooled (FC). If the applied field is about 1O\\\"{e} the material is zero-field cooled (ZFC). To explore the magnetic and thermodynamic properties of these materials we consider two-sublattice spin system, defined on the bcc lattice, with spin-$s^A$ operators $\\bf{S_{i}^A}$ at the sublattice $A$ site and spin-$s^B$ operators $\\bf{S_{i}^B}$ at the sublattice $B$ site, where $s^A>s^B$.
