The compensation behaviors and phase transitions of a new 3D fullerene-like polymer are explored by using Monte Carlo method. The ground-state phase diagrams and magnetization profiles are given, and the conditions for the occurrence of the compensation temperature Tcomp are obtained. As classified in Néel theory, N-type and P-type magnetization curves are found. To explore the changes in the transition temperature TC and the compensation temperature Tcomp induced by physical parameters, we also present the phase diagrams. Furthermore, the critical exponents of the system are calculated, and a good agreement can be achieved by comparing our results with others'. Finally, the triple hysteresis loops are discovered.

In this study, a bilayer Kagome lattice with RKKY interaction is described using a ferrimagnetic mixed spin-3/2 and spin-2 Ising model. Interesting compensation temperature and hysteresis loops of the system generated by various physical parameters, such as the crystal fields of sublattices (D a , D b), the interlayer exchange coupling (J R) and the intralayer exchange coupling (J b) are explored using Monte Carlo simulation. The results demonstrate that the compensation temperature (T comp), weaker D a and J b , and stronger D b , are favourable for the emergence of the compensation temperatures. Besides, under certain physical parameters, the system may exhibit triple-loop hysteresis behavior and multiple magnetization plateaus. • A ferrimagnetic mixed-spin (3/2, 2) Ising model on the bilayer Kagome lattice with RKKY interaction was proposed. • The effects of the crystal field, exchange coupling and non-magnetic layer were studied. • Magnetization, partial magnetization, and susceptibility were discussed. • Phase diagrams of the critical and compensation temperatures were obtained. • Interesting multi-loop hysteresis characteristics and magnetization plateaus were found.

In recent years, borophene has developed into an incredibly promising magnetic material that is essential to many industries including superconductivity and fuel cells. In this paper, using Monte Carlo simulation, the ground-state phase diagrams and magnetic properties of an Ising-type borophene monolayer are explored specifically. The results show that induced by crystal field and exchange coupling, the second-order magnetic phase transitions and the compensation temperature are obtained. Additionally, the multiple compensation temperatures and multi-loop hysteresis characteristics are observed, which are vital in multiple magnetic recording. • A mixed-spin Ising-type borophene monolayer was studied based on Monte Carlo simulation method. • The ground-state phase diagrams were discussed by Monte Carlo method. • The temperature dependence of the magnetization and the susceptibility were presented. • Multiple compensation temperatures were obtained. • Multiple-loop hysteresis behaviors were clearly observed in this system.

In this study, we use Monte Carlo simulation to analyze the magnetic properties of the ferrimagnetic CrI3-like structure with mixed spin (3/2, 1) structures. We start from the ground-state phase diagrams, and then discuss magnetization, magnetic susceptibility, internal energy, specific heat and phase diagrams of critical temperature, and finally present hysteresis loops induced by different parameters. It is found that the CrI3-like structure can show compensation temperature, rich temperature-dependence magnetization curves and magnetic multi-hysteresis loops behaviors such as double-loop, triple-loop and quintuple-loop. • A ferrimagnetic mixed-spin (3/2, 1) Ising model was proposed for CrI 3 -like structure with periodic boundary condition. • The effects of crystal field, exchange coupling and external magnetic field were studied. • Magnetization, magnetic susceptibility, internal energy, specific heat were discussed. • The phase diagrams of the critical temperatures were presented. • Interesting multi-loop hysteresis phenomenon were found.
