We apply Monte Carlo simulation using the Metropolis single spin flip algorithm to study the magnetic and thermodynamic properties of a ferrimagnetic mixed-spin, 
and 
alternating on a square lattice. The ground state phase diagrams are obtained for different parameters characterizing the system. The effects of the exchange coupling, the crystal field, the external magnetic field and the temperature on the magnetization, the specific heat, the compensation points and hysteresis loops are discussed in detail. The obtained results show that the studied system exhibits a compensation phenomenon, which depends on the combination of parameters in the Hamiltonian. Under certain physical parameters, multiple cycle hysteresis loop patterns have been observed in the system. It is found that the various parameters characterizing the Hamiltonian and the temperature strongly affect the coercivity and the remanence magnetization of the system. Comparing our results with other theoretical and experimental studies, a good agreement has been obtained qualitatively.
