“…For example, the effective-field theory with correlations (EFT) is an approximate method proposed by Kaneyoshi et al for solving the Ising model [22,23]. Afterwards many scientists have subsequently utilized this method to calculate and successfully explain the magnetic behavior of various nanostructures [24][25][26][27]. Bobák et al by employing this method to investigate the phase diagrams of honeycomb lattice, the square and simple cubic lattices with mixed spins and obtained tricritical points and compensation point [28][29][30].…”

By employing effective-field theory with correlations, the effects of exchange couplings and anisotropies on the physical properties of graphyne-like sandwich structure with a mixed-spin (5/2, 2) were analyzed. The various characteristic curves of the hysteresis loops, magnetization, susceptibility, internal energy, specific heat, as well as phase diagram was obtained. We found the multiple-loop hysteresis behaviors and reentrant phenomenon under certain conditions. Moreover, we also depicted the variation curves of dynamic magnetization under the impact of a periodically oscillating magnetic field. It is shown that a time-dependent and independent magnetic field can control and induce the disorder and order of the system.

The triangular-type Ising nanowire is constructed on the Bethe lattice (BL) by using the core-shell structure consisting of spin-3/2 atoms as the core and spin-1/2 atoms as the triangular shell. Each triangular plaquette of spins forms a nanoparticle which is connected to upper and lower plaquettes symmetrically. The additions of the plaquettes continue indefinitely until the thermodynamic limit to construct the nanowire. The inter- and intra-bilinear interaction parameters (J) are assumed to be positive or negative to simulate the ferromagnetic (FM) or antiferromagnetic (AFM) interactions, respectively. The crystal field for spin-3/2 and external magnetic field for all sites are also included into the model. After obtaining the formulation of the model in terms of exact recursion relations (ERRs), the thermal variations of magnetizations are studied in detail to obtain the phase diagrams. It is found that the model leads to different types of FM and AFM regions with various forms of phase transitions. It is also interesting that the model presents random or oscillatory magnetization behavior regions for the appropriate values of our system parameters.
