“…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.

“…Experimentally, the core/shell nanostructures, such as core/shell nanowires and core/shell nanotubes have been widely studied [12][13][14][15][16][17][18][19]. Furthermore, by using a variety of theoretical techniques, mainly effective-field theory (EFT) [20][21][22][23][24][25][26][27][28], Bethe Lattice [29][30][31], mean-field theory (MFT) [32][33][34][35], and Monte Carlo simulations (MCS) [36][37][38][39][40][41][42][43], and the magnetic properties of core/shell nanostructures have also been studied. Similarly, magnetically segmented nanostructures composed of alternating ferromagnetic or nonmagnetic materials have been extensively explored [44][45][46][47][48][49][50].…”

This study explores the presence of diverse phase diagrams and hysteresis characteristics, as well as their dependencies on segment dilution, in an Ising-type core/shell segmented nanostructure. The magnetic and hysteretic behaviors of the nanostructure were carefully investigated by employing the effective-field theory, and its respective diluted parameters. The phase diagrams reveal characteristic phenomena that are influenced by the dilution parameters. Specifically, this study examined the variations in phase transitions and tricritical points by altering the dilution and physical parameters of the segments. The investigation also encompasses an examination of the hysteresis characteristics, including the hysteresis loop, coercivity and remanence, in relation to the segment dilution dependence of the segmented nanowire. It was discovered that as the temperature rises, the hysteresis loop areas diminish. However, intriguingly, at specific dilution and crystal area values, the hysteresis loop areas exhibit an augmentation.

“…In addition, the nanowires are characterized by a very high surface-bulk ratio compared to the bulk materials. Theoretically, the magnetic properties of nanowires have been widely investigated by the use of different approaches, including Monte Carlo simulation (MCS) (Hachem et al, 2018;Aharrouch et al, 2020;Boughrara et al, 2014), effective-field theory (EFT) with correlations Kantar and Kocakaplan, 2014;Kocakaplan and Ertaş, 2015), mean-field approximation (MFA) (Michael et al, 2007;Kantar and Ertaş, 2014a;Ertaş and Kantar, 2015) and exact recursion relations on the Bethe lattice (Albayrak, 2017). Experimentally, the magnetic nanowires such as CoPt, Fe 3 O 4 , Fe 14 Ni 86 and ZnO can be synthesized by various techniques, such as electrodeposition into anodic aluminum oxide templates (Gao et al, 2008;Zhang and Zhang, 2009;Zhu et al, 2001), vapor transport process (Fan and Lu, 2006) and nanolithography (Chou et al, 1996).…”

PurposeThe purpose of this article is to investigate the magnetic properties and the hysteresis loops behavior of a ferrimagnetic cubic nanowire with mixed spins SA = 3/2 and SB = 2.Design/methodology/approachWe have used the Monte Carlo simulation to examine the influences of the exchange interaction JB, the crystal field ∆ and the temperature on the magnetic properties and hysteresis loops of the nanowire. More exactly, we have shown the temperature dependence of the sublattice magnetizations (mA and mB) and the total magnetization (M) for several values of the Hamiltonian parameters, as well as the corresponding phase diagrams. Finally, the effect of an external magnetic field is studied by plotting the hysteresis loops of the system for different values of exchange interaction, crystal field and temperature.FindingsThe obtained results show the existence of second-order phase transitions, as well as the compensation behavior. Moreover, according to the values of the Hamiltonian parameters, the system can exhibit one, two or three hysteresis loops.Originality/valueThe magnetic nanowires are of great interest in experimental works, but without theoretical explanations, the experimental results cannot be clarified in depth. For this, we contribute through this theoretical study to understand the nanowires, especially those with mixed spins (2, 3/2).
