Study of the coupling effect on the wetting of a mixed Ising model

Magnetic properties of ferromagnetic sites have been studied using Monte Carlo simulations within the Ising model framework. The considered Hamiltonian includes first nearest-neighbor, an external magnetic field and a crystal field. The thermal magnetizations and magnetic susceptibilities have been computed for a fixed size. The critical temperatures have been deduced. The magnetization versus the exchange interactions and crystal field have been studied for a fixed system size, N = 4 sites (N refers to the number of sites in the z-direction.). The magnetic hysteresis cycle versus temperature has been established. The saturation magnetization and the coercive filed have been deduced. The magnetization versus the dilution x has been deduced for different values of the temperature and for a fixed size, N = 4 sites.
