The mixed spin-12 and spin-S(S=1,32,52,72) Ising ferrimagnetic systems with a crystal field are studied within the framework of the exact recursion relations on the Bethe lattice. The phase diagrams and thermal behaviors of magnetizations are investigated numerically for the different values of...

The effects of both an exchange anisotropy and a single-ion anisotropy on the phase diagram and the compensation temperature of the mixed spin-1 and spin-12 Heisenberg ferrimagnet are investigated by the use of an Oguchi approximation. Particular emphasis is given to the simple cubic lattice...

Critical and compensation properties of a mixed spin-1 and spin-3/2 Ising ferrimagnet on a square lattice are investigated by standard and histogram Monte Carlo simulations. The critical temperature is studied as a function of single-ion anisotropy strength. The second order of the phase...
