“…On the other hand, various theoretical and experimental investigations have been carried out for the two-sublattice mixed-spin Ising systems (Masrour and Jabar, 2020; Jabar and Masrour, 2019; Masrour and Jabar, 2018, 2019; Bouda et al , 2019; Zahir et al , 2019; Lafhal et al , 2019); the reason is mainly related to their importance for studying bimetallic molecular systems with ferrimagnetic properties (Kahn, 1993), magneto-optical recording materials (Mansuripur, 1995) and information storage technologies (Prinz, 1998). Also, these systems show a variety of interesting phenomena in comparison with their single-spin counterparts.…”

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.
