Magnetic Behavior of Ising Nanowire with Mixed Integer Spins: A Monte Carlo Study

Abstract: 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 behavior… Show more

“…In contrast, the negative exchange interaction between the core and the shell also leads to the appearance of multiple loops. Similar behaviors can be seen in previous studies of nanowires, [ 32,61–63 ] ferrimagnetic nanoisland, [ 64 ] multilayer, [ 65 ] and the BiFeO3$\left(\text{BiFeO}\right)_{3}$/YMnO3$_{3}$ antiferroelectric/ferroelectric Ising bilayer system. [ 66 ] Experimentally, triple and double hysteresis loop behaviors have been witnessed in nanoparticles, [ 67 ] and in various Py/Cu$\text{Py/Cu}$, CoFeB/Cu$\text{CoFeB/Cu}$, CoNiP/Cu$\text{CoNiP/Cu}$, FeGa/Py$\text{FeGa/Py}$, and FeGa/CoFeB$\text{FeGa/CoFeB}$ multilayered nanowires.…”

“…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].…”
