“…Therefore, a layered ferrimagnetic mixed spin-2 and spin-5/2 Ising model has been employed to describe the above-mentioned molecular-based magnets. Theoretically, many works have been extended to the ferrimagnetic mixedspin system by different methods, such as the Monte Carlo (MC) simulation [4,5], the effective-field theory (EFT) [6][7][8][9], the mean-field approximation [10,11], the Green's function approach [12][13][14], and so on. It is found that most of these studies deal with magnetic properties, internal energy, specific heat, the initial susceptibility, the compensation behavior, tricritical points without external magnetic field.…”

Monte Carlo simulation has been used in detail to study the step effect of the hysteresis loop for a ferrimagnetic mixed spin-2 and spin-5/2 Ising model on a honeycomb lattice. The results indicate that the hysteresis loops exhibit an obvious step effect and various shapes for different single-ion anisotropies and exchange couplings at very low temperature. Under a longitudinal magnetic field (h > 0 or h < 0), we have obtained 2S þ 1 magnetic plateaus for different single-ion anisotropies at low temperature. The existence of triple and double hysteresis loop patterns has been found in the system. It is shown that the sublattice anisotropy and the interlayer exchange coupling strongly affect the coercivity of the system. The influence of the interlayer exchange couplings on the total magnetization, susceptibility, internal energy and specific heat with temperature are numerically examined in the absence of the longitudinal field.

“…It is worth noting that there are a few works dealing with the layered mixed spin-2 and spin-5/2 Ising system on the honeycomb lattice [11][12][13][14][15][16] since the system is related to a molecular-based magnet AFe II Fe III (C 2 O 4 ) 3 (A = N(n-C 3 H 7 ) 4 ) [17], and particularly interesting is the fact that the magnetic transition-metallic ions in the magnets can be replaced by other metal ions if the valencies of the ions are not changed. Thus, theoretically, molecular-based magnetic materials containing two integer spin sublattices or two half-integer spin sublattices with similar crystal structures can be synthesized if the experimental ingredients are changed.…”

The study of the phase diagram and internal energy of the mixed spin‐3/2 and spin‐5/2 ferrimagnetic Ising system with interlayer coupling by effective‐field theory; a simple approach of calculating internal energy

Phase diagrams and internal energies of a layered Ising system were studied using the effective-field theory (EFT) with correlations. The results show that the critical temperature becomes larger, while the compensation temperature and the internal energy become smaller with the increase in the interlayer coupling and the crystal-field. The traditional method to calculate the internal energy of the Ising system by the EFT is based on a differential of its differential operator identity. So an additional differential procedure must be carried out when calculating the internal energy. In this paper, a new function on which the differential operator acts is introduced to solve this problem, without performing the additional differential procedure. The results obtained by the two methods are exactly the same.

“…They showed that the phase diagram in the plane magnitude of spin-1 exchange interactions versus crystal field intensity exhibits a very narrow region of compensation points. In addition, the influence of a transverse field on the compensation point was examined on honeycomb and square lattices [9][10][11].…”

a b s t r a c tIn this study, dependence on site dilution of critical and compensation temperatures of a twodimensional mixed spin-1/2 and spin-1 system has been investigated with Monte Carlo simulation. The dependence of the thermal and magnetic behaviors on dilution of mixed spin system has been discussed. We have shown that the critical and compensation temperatures of diluted mixed spin system linearly decrease with increasing number of diluted sites.
