“…The coexistence of a negative exchange interaction between the core and the shell with the positive exchange interaction in the core and the shell separately is the main reason beyond the occurrence of the compensation phenomenon. It is noteworthy that similar phase diagrams have been observed in other nanosystems such as cylindrical ferrimagnetic nanotube with core-shell structure, [38] cylindrical Ising nanowire, [28,30] Ising nanoparticle, [45] rectangle Ising nanoribbon, [46] checkerboard square structure, [47] and three-layer system of hexagonal structure. [48] It should be noted that the first order and the critical end point are not studied in these references.…”

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.

“…The study of magnetic nanowires have important technological applications in various areas such as nano-medicine [10,11], information processing and magnetic recording [12]. 6 Theoretically, a multitude of approximations have been used to determine the magnetic properties of nanowires, in particular the mean field approximation (MFA) [13,14], the effective field theory (EFT) [14][15][16][17][18], the Monte Carlo simulation (MCS) [19][20][21][22][23] and the exact recursion relations on the Bethe lattice [24].…”

The magnetic and thermal properties of a ferrimagnetic mixed spin-1 and spin-2 cubic Ising nanowire are studied by using the Monte Carlo simulation. The influences of the nearest (JAB) and next-nearest neighbor (JA and JB) exchange interactions and the single-ion anisotropies (DA and DB) on the critical and compensation temperatures are illustrated. Moreover, the phase diagrams on the (temperature, anisotropy) plane are plotted for several values of JA/|JAB|. The system shows very rich and interesting behaviors, namely first and second order phase transitions, tricritical points and compensation phenomenon. Finally, the dependence of hysteresis loops on the anisotropies, the exchange interactions and the temperature is also investigated.

“…1 was simulated using the Monte Carlo simulation method based on the Metropolis algorithm [44], and periodic boundary conditions were applied. The procedure followed is similar to the procedure discussed in previously published papers from this group [18,42,43]. A 400,000 step was used to equilibrate the system, and then data was generated for 450,000 MC steps per spin.…”

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.
