Magnetic and thermodynamic properties of a ternary metal nanoisland: A Monte Carlo study

Using the Monte Carlo simulation, the magnetic and thermodynamic properties of a ferrimagnetic mixed-spin (1, 3/2, 2) ternary metal nanoisland with core-shell structure in external magnetic field have been researched detailedly. The effects of crystal-field, exchange coupling and temperature on magnetization, susceptibility, blocking temperature and internal energy as well as hysteresis loops behavior of the system have been exhibited. Some interesting phenomena such as multiple saturation magnetizations and rich hysteresis loops behaviors have been found. The results can be comparable with some theoretical and experimental researches.
