Thermodynamic properties of the mixed spin-3/2 and spin-1/2 Heisenberg model are examined within the Oguchi approximation in the presence of a random crystal-field (RCF). The RCF is either introduced with probability p or turned off with probability

We used mean-field theory based on the Bogoliubov inequality for the Gibbs free energy to examine the magnetic properties of a mixed spin-5/2 and spin-7/2 Blume-Capel ferrimagnetic system. The thermal behaviours of the system magnetization are classi

The magnetic properties of the mixed spin-1/2 and spin-7/2 Ising model with a crystal-field in a longitudinal magnetic field are investigated on the Bethe lattice using exact recursion relations. The ground-state phase diagram is constructed. The tem

The mixed spin-1/2 and spin-5/2 Ising model is investigated on the Bethe lattice in the presence of a magnetic field h via the recursion relations method. A ground-state phase diagram is constructed which may be needful to explore important regions o

The transverse antiferromagnetic spin-[Formula presented] Ising model is studied within the effective field theory with correlations for a finite cluster with random bond dilution and random longitudinal magnetic field effects. The bonds are either r

The magnetic properties of the spin-5/2 Blume-Capel model are investigated by means of the Mean-Field theory in a random single-ion anisotropy environment. The T = 0 phase diagram is singled out as well as the thermal behaviors of the lattice magneti

In this paper, the effects of the longitudinal [Formula: see text] and the transverse [Formula: see text] crystal fields on the mixed spin-[Formula: see text] Ising–Heisenberg model have been studied. The thermodynamic properties of the model are o
