“…Finally, the hysteresis loops disappear for temperatures above the critical temperature as for T/|J AB | = 12 in Figure 12 (d). These results are consistent with those obtained in some experimental (Zhang and Zhang, 2009; Garcia et al , 2010; Manikandan et al , 2015) and theoretical works (Hachem et al , 2018; Alrajhi et al , 2018; Wang et al , 2016; Kantar, 2016; Ertaş, 2016).…”

“…This phenomenon exists in mixed-spin systems under certain conditions and has interesting technological applications, especially the thermomagnetic recording materials and magneto-optical devices (Mansuripur, 1995; Prinz, 1998; Kostishyn et al , 2014). As examples, the compensation behavior has been observed in some mixed-spin nanostructures as for nanowires (Ertaş and Kantar, 2015; Alrajhi et al , 2018; Wang et al , 2016; Alzate-Cardona et al , 2017; Benhouria et al , 2017), nanotubes (Wang et al , 2018; Mi et al , 2018) and nanoparticles (Zaim et al , 2016; Dakir et al , 2015).…”

“…In particular, the research on magnetic nanowires has been receiving considerable attention experimentally; the nanowires Fe 3 O 4 , Co–Cu and CdO can be synthesized by diverse techniques, such as a simple metal displacement deposition method (Yang et al , 2011), an electrodeposition method followed by heat-treating processes (Zhang and Zhang, 2009) and a vapor transport process (Kuo and Huang, 2006). Theoretically, several approaches have been used to investigate the magnetic properties of nanowires, namely, effective field theory with correlations (Kaneyoshi, 2017; Kantar, 2018; Kocakaplan and Ertaş, 2015), mean field approximation (Ertaş and Kantar, 2015; Kantar and Keskin, 2016; Mendes et al , 2018a, b; Masrour et al , 2016), recursion relations on the Bethe lattice (Albayrak, 2016), Monte Carlo simulation (MCS) (Hachem et al , 2018; Alrajhi et al , 2018; Wang et al , 2016; Benhouria et al , 2018; Mendes et al , 2019) and self-consistent ab-initio calculations (Masrour et al , 2014).…”

PurposeThe purpose of this paper is to study the magnetic properties and the hysteresis behavior of a ferrimagnetic cubic Ising nanowire with mixed spins S = 3/2 and S = 5/2 in which the atoms are placed alternately.Design/methodology/approachIn order to investigate the effects of the exchange interactions and crystal field on the magnetic properties and hysteresis behavior of the nanowire, we have used the Monte Carlo simulation. More precisely, we have plotted the thermal variations of the sublattice and total magnetizations for different values of the Hamiltonian parameters, and we have presented the corresponding phase diagrams. In addition, the influence of an external magnetic field is examined by plotting the variations of hysteresis loops with the change of temperature and crystal field.FindingsAll phase transition found in this study are of second-order and the critical temperatures increase linearly with the increase of the exchange interactions. The compensation temperatures appear only for some domains of crystal field D and exchange interaction JB of the sublattice (B). Moreover, when studying the hysteresis behavior, the system can show one or double hysteresis loops.Originality/valueThe authors consider that this research is consistent with the scientific axis of the journal which benefits a great esteem in our country and in the world. In addition, the results are of technological interest.

“…[1][2][3][4][5][6] The variety of magnetic structures and spins combinations that have been analyzed by these mixed Ising models is quite wide. 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.…”

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.

In this paper, we investigate the magnetic behavior of a single-walled hexagonal spin-1 Ising nanotube by using the effective field theory (EFT) with correlations and the differential operator technique (DOT). The system consists of six long legs distributed parallel to each other on a hexagonal basis. Within each chain, spin sites are regularly positioned and magnetically coupled through a J // exchange interaction along the chains and J⊥ between adjacent chains. Key equations of magnetization, susceptibility and critical temperatures are established, numerically resolved and carefully analyzed for some selected exchange couplings and various applied magnetic fields. In addition to the phase diagram, interesting phenomena are noted, particularly for opposite exchange interactions where magnetization plateaus and frustration are discovered.
