The effect of single‐ion anisotropy is investigated on a mixed‐spin (1, 3/2) square Ising nanowire with square ferromagnetic shell and negative core–shell exchange coupling using Monte Carlo simulation. Depending on the Hamiltonian parameters, three different topologies of the phase diagram in the (anisotropy, temperature) plane are found. The tricritical point appears for and effects. For influence of , there is no tricritical point in the phase diagram. The first‐order lines and critical endpoints are also obtained. Some important phenomena such as compensation behavior and rich variety of hysteresis loops are found. The results can be compared with other works, in particular on the nanowire with core–shell structure.

“…On the other hand, Ising systems have recently been frequently used to model nanowire systems because of its simplicity. Theoretical and numerical approaches, including mean-field approximation, effective-field theory, cluster variational theory, and Monte Carlo simulations, have been extensively employed to study magnetic nanowire systems [29][30][31][32][33][34][35][36][37][38][39]. Among these approaches, effective field theory has been widely used as a powerful tool to investigate magnetic properties and understand the behavior of nanowires [40][41][42][43][44].…”

The paper focuses on the study of an Ising nanowire array composed of core/shell-structured single nanowires placed at the edges of a square lattice. The phase transition temperature, at which a transition occurs in the magnetic properties, is obtained using effective field theory for two interacting individual nanowires. To understand how the interaction affects the magnetic, we defined the exchange interaction (JR) between the single nanowires. This interaction is assigned both positive and negative values to reveal the ferromagnetic and antiferromagnetic characteristics of the system. Our results revealed that the exchange interaction between individual nanowires significantly influences the magnetic properties of the system.

In this paper, the ferrimagnetic mixed spins (1, 5/2) Blume-Capel model is proposed to investigate the phase diagrams and hysteresis behaviors of a magnetic cylindrical nanotube with a core-shell structure using the mean-field approximation based on the Bogoliubov inequality for the Gibbs free energy. The core sites are occupied by σ= ±1, 0 spins, whereas the shell sites are filled by S= ±5/2, ±3/2, ±1/2 spins. The effects of exchange couplings (Jin, JS) and single-ion anisotropies (DC, DS) on core, shell, and total magnetizations are investigated, as well as hysteresis behaviors. The entropy, free energy, and specific heat are analyzed to establish the stability of the solutions. The presentation and discussion of phase diagrams is detailed. The system shows a first-order and second-order phase transitions, as well as tricritical and critical end- points. In addition, the system shows compensation and reentrant behaviors. Various multiple hysteresis loop behaviors are seen according on the Hamiltonian parameters, such as the presence of triple, quintuple, and septuple hysteresis loops.
