“…We should also mention that since the some similar typical results for the dynamic magnetization curves for different magnetic phase states were given by Refs. [50,56,[62][63][64], we do not present the dynamic magnetizations curves in order to avoid some overlaps.…”

Influences of crystal-fields (DA and DB) and interlayer coupling interactions (J3) on dynamic magnetic critical behaviors of a mixed-spin (3/2, 2) bilayer system under an oscillating magnetic field are investigated by the Glauber-type stochastic dynamics based on the mean-field theory. For this purpose, dynamic phase diagrams are constructed in the reduced temperature and magnetic field amplitude plane for the ferromagnetic/ferromagnetic (FM/FM), antiferromagnetic/ferromagnetic (AFM/FM) and AFM/AFM interactions in detail. We observe that the influences of DA, DB and J3 interactions parameters on the behavior of the dynamic phase diagrams are very much.

“…In Refs (Guo-Zhu and Hai-Ling, 2009;Abubrig, 2013), the authors have investigated the phase diagrams of this mixed-spin system within MFA. We also cite two other works that have studied the non-equilibrium behavior of the mixed spin-3/2 and spin-2 Ising system on square lattice under a time-dependent external magnetic field by using the Glauber-type stochastic dynamics (Keskin and Polat, 2009;Temizer et al, 2014). All these studies show the presence of a wide variety of multicritical phenomena, especially the phase transitions of first-and second-order, the tricritical points and the compensation temperatures.…”

PurposeThe purpose of this article is to investigate the magnetic properties and the hysteresis loops behavior of a ferrimagnetic cubic nanowire with mixed spins SA = 3/2 and SB = 2.Design/methodology/approachWe have used the Monte Carlo simulation to examine the influences of the exchange interaction JB, the crystal field ∆ and the temperature on the magnetic properties and hysteresis loops of the nanowire. More exactly, we have shown the temperature dependence of the sublattice magnetizations (mA and mB) and the total magnetization (M) for several values of the Hamiltonian parameters, as well as the corresponding phase diagrams. Finally, the effect of an external magnetic field is studied by plotting the hysteresis loops of the system for different values of exchange interaction, crystal field and temperature.FindingsThe obtained results show the existence of second-order phase transitions, as well as the compensation behavior. Moreover, according to the values of the Hamiltonian parameters, the system can exhibit one, two or three hysteresis loops.Originality/valueThe magnetic nanowires are of great interest in experimental works, but without theoretical explanations, the experimental results cannot be clarified in depth. For this, we contribute through this theoretical study to understand the nanowires, especially those with mixed spins (2, 3/2).

“…Abubrig highlights the same model with different single-ion anisotropies using the mean field theory based on the Bogoliubov inequality for the Gibbs free energy (Abubrig, 2013a). In addition, the nonequilibrium behaviors of mixed spin-3/2 and spin-2 Ising bilayer systems are studied via the Glauber-type stochastic dynamics by Temizer et al (2014) and Keskin and Ertaş (2017). The critical and compensation behaviors as well as the phase diagrams of Ising systems with mixed spins S = 3/2 and S = 2 are investigated using the exact recursion equations on the Bethe lattice by Albayrak (2007) and Karimou et al (2015).…”

PurposeThe authors investigate the magnetic properties of a mixed spin-3/2 and spin-2 Blume-Capel model on square and cubic lattices with two different single-ion anisotropies.Design/methodology/approachTo study the critical behavior of a mixed spin-3/2 and spin-2 system, the authors have used a real space renormalization group approximation and specifically the Migdal-Kadanoff technique. The authors give the phase diagrams for two different cases: (1) on the (Δ/|J|, 1/|J|) plane with ΔA = ΔB = Δ, and (2) on the (ΔA/|J|, 1/|J|) and (ΔB/|J|, 1/|J|) planes for selected values of ΔB/|J| and ΔA/|J|, respectively.FindingsThe phase diagrams obtained show that the system exhibits both second- and first-order phase transitions as well as tricritical points for some values of the anisotropies. Moreover, using the variation of the free energy and its derivative at low temperatures, the authors have seen the appearance of first-order transitions at very low temperatures.Originality/valueFew investigations of mixed spin-3/2 and spin-2 systems with crystal field have been realized. For this reason, the authors use the renormalization group approach to complete the work done on these systems. In absence of an exact solution, this contributes to the synthesis of the approximation results on mixed spins models.
