Magnetic properties of a nanoscaled ferrimagnetic thin film: Monte Carlo and effective field treatments

The magnetic properties of a spin-1/2 Ising nanoscaled thin film with anti-ferromagnetic interfacial coupling between the surface and the next layer are investigated. This has been done by using the two theoretical frameworks of the effective field theory, based on a probability distribution method, and the Monte Carlo simulation. The influence of the system parameters on the phase diagram, on the internal energy and on some other magnetic proprieties of the system are examined. We have found that the nanoscaled thin film exhibits a compensation temperature and triple hysteresis loops for appropriate values of the system parameters.
