Magnetic and thermodynamic properties of a cylindrical ferrimagnetic Ising nanowire with core/shell structure

The Monte Carlo simulation has been used to study the magnetic and thermodynamic properties of a cylindrical ferrimagnetic Ising nanowire system with core/shell structure. Phase diagrams are attained with diverse single-ion anisotropies and exchange couplings. It is discovered plentiful phase transitions in the nanowire system, for example, the compensation behaviors, the second-order and first-order phase transitions as well as the tricritical point phenomena. We have discussed the significant effects of single-ion anisotropies, exchange couplings and temperature on the magnetization, the susceptibility, the internal energy and the specific heat for the cylindrical core/shell nanowire system. In addition, we have also found the existence of two types of triple hysteresis loops behaviors for certain physical parameters. It is interesting to achieve satisfying results to compare our results obtained with other theoretical and experimental studies. ]
