要旨:
In this work, the mixed spin Ising nanowire model consisting of a spin-1 ferromagnetic core, which is surrounded by a spin-1/2 ferromagnetic surface shell is studied in the presence of magnetic and crystal fields using of the Monte Carlo (MC) Simulations based on the heat bath algorithm. We assume that the exchange interaction between two nearest-neighbor spins at the surface shell and the core is antiferromagnetic. We have examined the effects of the surface and the crystal field on the critical and compensation temperatures. The thermodynamic properties, the hysteresis behaviors are also studied. For appropriate values of the system parameters, the compensation point and multi-loops are found.
