A Monte Carlo Simulation (MCS) has been used to study critical behavior and magnetic properties of a decorated Ising film on a cubic lattice structure. The system consists of two magnetic atoms species A and B with σA=1/2 and SB=1, where the B sites decorate the bonds between A sites. The...

The spin-1/2 Ising model on a square lattice, with fluctuating bond interactions between nearest neighbors and in the presence of a random magnetic field, is investigated within the framework of the effective field theory based on the use of the differential operator relation. The random field...
