“…This assumes the presence of a barrier concerning the magnetic excitations [31]. Similar behaviors were observed in a square spin-½ nanotube when diagonal exchange coupling is included [32], and in other frustrated systems [33,34]. Now, we present the dependence of total magnetization on external magnetic field for different temperatures for s = ½ and exchange anisotropy J' = -0, 5 in Fig.…”

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.
