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.

“…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.
