Magnetic properties of the three dimensional Ising model with interface single-ion anisotropy
Abstract
Within the framework of effective-field theory, we investigate the effects of an interface single-ion anisotropy on the magnetic properties in the simple cubic spin-1/2 Ising model. We find a new tricritical behavior of the interface magnetization depending on the strength of the ferromagnetic perpendicular exchange interaction the spin between the spins at the interface and their neighbors in the next layers in the right and left sides. The magnetic behavior of an interface coupled antiferromagnetically to the two sides is also examined.
