“…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).…”

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.

“…Our calculations show that the appearance of the two points of compensation is sensitive to the value of interlayer coupling to get two points of compensation. Therefore, the single-ion anisotropy plays a significant factor in the foundation of the second compensation temperature [47].…”

The magnetic properties and phase diagrams of the mixed spin-1/2 and spin-1 Ising model on a honeycomb inside a hexagonal structure have been studied using the Monte Carlo simulations based on the Metropolis update protocol. The effect of different exchange interactions (intralayer and interlayer Js') and single-ion anisotropy D on the magnetic properties, transition and compensation temperatures, and magnetic susceptibility have been investigated. The phase diagrams, T-J and T-D, for different exchange interactions and crystal field values have been examined. Compensation behavior exists for critical values of interlayer's exchange interactions. Our calculations reveal the existence of two points of compensation for a narrow range of negative D. Article highlights A mixed spin Ising model on a centered honeycomb-hexagonal structure was proposed The effects of crystal field and exchange coupling were studied Two points of compensation temperature were exist.
