“…To consolidate our results, we highlight a recent work of Strecka et al, in which they studied the thermodynamic behavior in a frustrated spin-1/2 Ising-Heisenberg triangular tubes composed of Heisenberg spin triangles mutually coupled by the Ising inter-triangle interaction, using the transfer matrix method [35]. They demonstrated that the intermediate plateaus become smaller and the sharp edges associated with the magnetization jump become rounder with increasing temperature by considering the antiferromagnetic interaction.…”

We studied some magnetic behaviors of the Ising model in a triangular spin tube using the effective field theory (EFT) with correlations. We examined the effects of exchange anisotropy, and temperature T on the magnetic properties of the spin ½ Ising model in a triangular spin tube, particularly for isotherm magnetization, spontaneous magnetization, and magnetic susceptibility. We investigated the magnetic properties of the triangular spin ½ tube in detail. At low temperature, magnetization curves of a triangular spin ½ tube of the Ising model with the intra-triangular J ┴, and inter-triangular J // interaction exchange are examined within the behavior magnetic. It is shown that the developed model satisfactorily describes all pronounced features of the low-temperature magnetization process and the magnetothermodynamics such as abrupt changes of the isothermal magnetization curves, a giant magnetocaloric effect. Among the most notable features of zero-temperature magnetization curves, one could mention fractional magnetization plateaus, quantum spin liquids, and macroscopic magnetization jumps, which can be found first of all in frustrated quantum Heisenberg spin models.

In this paper, the magnetic and thermodynamic properties of an Ising-type polyhedral chain with mixed spin-5/2 and spin-1 were studied in detail by the Monte Carlo method. The system can display multiple saturation values and abundant profiles of magnetization induced by different physical parameters during the change of temperature. In addition, we also obtained interesting behaviors of susceptibility, internal energy, specific heat, magnetic entropy, magnetization plateaus, depending on the competition among various physical parameters. Finally, multi-loop hysteresis behaviors including triple-loop and quintuple-loop were observed.

“…During the current decade, a number of exact results on the MCE in the so-called Ising-Heisenberg one-dimensional spin models have been obtained [32][33][34][35][36][37]. The main feature of these models is the special alternation of the small clusters of quantum spins and Ising interaction bond in such a way that the local Hamiltonians for the blocks commute with each other.…”

The magnetic and magnetocaloric properties of the mixed spin-(1/2,1) Ising-Heisenberg model on a two-leg honeycomb ladder with dimer-rung alternation are exactly examined under an adiabatic demagnetization process using the classical transfer-matrix formalism. We notify that the magnetization curve of the model exhibits plateaux as a function of the applied magnetic field and cyclic four-spin Ising interaction at certain rational fractions of the saturation value. It is evidenced that the model manifests an enhanced magnetocaloric effect in a proximity of the magnetization steps and jumps, accompanying with the plateaux and jumps of correlation function of the dimer spins. We conclude that not only the cooling/heating capability of the model could be pleasantly demonstrated by the applied magnetic field variations, but also a typical cyclic four-spin Ising interaction plays essential role to determine an efficiency of the magnetocaloric effect of the model.
