Popis: | The Monte Carlo simulation has been applied to study the magnetic behaviors of a ferrimagnetic mixed-spin (1, 2, 5/2) Ising nanoisland with bilayer hexagonal core-shell structure in an external longitudinal magnetic field. We have investigated the influences of the anisotropies, the exchange couplings, the longitudinal field and temperature on magnetization, susceptibility, internal energy and hysteresis loop of the present nanoisland. The behavior of the X parameter (the magnetization, susceptibility, internal energy and blocking temperature) as a function of the parameter is studied. Particularly, the multiple hysteresis loop behaviors have been discovered, such as triple, quintuple, septuple, ninefold and elevenfold hysteresis loops under certain physical parameters. |
