Abstract: The magnetic properties of a decorated two-sublattice ferrimagnetic Ising model consisting of two magnetic atoms A and B with spins SA (SA = 12) and SB (SB > 12) are investigated within the framework of the effective-field theory with correlations. The uniaxial crystal-field interaction D exists on the B atoms and the effects of SB and D on the magnetic properties are examined. We find a number of characteristic phenomena in these quantities, such as the possibility of two compensation points and the two (or three) transition temperatures, not predicted in the Neel theory.
