摘要

This work systematically investigates the magnetic behavior of the ferrimagnetic Ising-type nanotube encapsulated with X70 described by the mixed-spin (2, 5/2) Ising model using Monte Carlo simulations. The analysis focuses on thermodynamic quantities including magnetization, magnetic susceptibility, specific heat, magnetic entropy under the effects of various physical parameters, especially concentrating on the ground-state phase diagrams, phase diagrams including blocking temperature and compensation temperature, multi-loop hysteresis behaviors. The system displays multiple spin configurations in ground state phase diagrams, double compensation temperatures, and abundant multi-loop hysteresis loops.
