“…Some examples are as follows: nanostructures such as nanographene layers alternated with spins 1/2, 3/2, and 5/2 that have compensation points in the presence of an external magnetic field, [7,8] cluster dendrimers (CD) of core/shell (CDCS) with the (3/2-2) spin mixture, and a mixed spin-(2-3/2) Heisenberg single-walled nanotube superlattice, [9,10] Ising nanoribbons, [11] Ising nanocubes, [12] Ising nanowires, [13,14] and nanoislands. [15] The dynamical behavior of these mixed Ising structures in the presence of oscillating magnetic fields has been the object of many recent studies, particularly the dynamical hysteresis loops [16][17][18] and the dynamical compensation temperatures. [19][20][21] Combinations of half-integer Ising models have been useful to characterize and model some crystal lattices.…”

Mean field and Monte Carlo simulations techniques are applied to study the behavior of a mixed Ising spin model in a square lattice where spins 7/2 are located in alternating sites with spins 3/2. There is an antiferromagnetic interaction between nearest neighbors, ferromagnetic interactions between next-nearest neighbors, crystal fields, and a magnetic external field. The role of the different interactions in the magnetic behavior of the system is explored. It is found that depending on the combination of parameters in the Hamiltonian this system presents multiple hysteresis loops, exchange bias, compensation temperatures, and discontinuous magnetizations. The results are compared with previous studies that do not include the ferromagnetic next-nearest neighbor interactions and found that they can have a strong effect in the magnetic behavior of the system.

“…The system exhibits also the reentrant phenomenon, that is we have two successive second-order transition temperatures (for example for D B /J 1 = −2.25, we have T C /J 1 = 0.18 and 1.2), a similar behavior has been found in Refs. [32] and [33]. For D A /J 1 = −3.5 and 0.0, in the phase diagram we have two lines separating the ordered and the disordered phases, one of the second-order for higher temperatures and the other of the first-order for lower temperatures which meet at a tricritical point.…”

Phase diagrams and magnetic properties of the mixed spin-1 and spin-3/2 Ising film with different single-ion anisotropies are investigated, by the use of Monte Carlo simulation based on heat bath algorithms. The effects of the crystal-fields and the surface coupling on the phase diagrams are investigated in detail and the obtained phase diagrams are presented. Depending on the Hamiltonian parameters, the system exhibits both second-and first-order phase transitions besides tricritical point, triple point, and isolated critical end point.

“…By applying firstprinciples density functional theory, Yue et al have studied magnetic properties of graphene nanoribbons with twisted zigzag-edged [29]. Furthermore, the various mixed-spin Ising models have been used to study the magnetic properties of system by different methods, such as effective-field theory (EFT) [30], Monte Carlo simulation [31] and mean-field theory [32]. By employing the Monte Carlo simulation, the ground-state phase diagrams of bilayer graphene described by the Ising model with mixed-spin (2, 3/2) are studied by Masrour and co-workers [33].…”

We employed the effective-field theory with correlations to study the hysteresis and thermodynamic properties of a bilayer graphene-like ring with edge decorated by a ferrimagnetic mixed-spin (2, 5/2) Ising model. The temperature dependence of magnetization, susceptibility, internal energy and specific heat of the system are illustrated in detail. As well, we depict the hysteresis behaviors and phase diagram with various parameters. The results showed the significance of the anisotropy, the magnetic field as well as the exchange coupling in controlling hysteresis behaviors and various magnetic quantities. The possibility of rich multiple-loop hysteresis and reentrant behaviors are found, sensitive to the competition among the physical parameters.
