Critical phenomena in Ising-type thin films by Monte Carlo study

• The magnetic properties of thin films are studied by Monte Carlo simulation.
• The critical temperature is obtained for different values of thickness of thin film.
• The magnetic hysteresis cycle is obtained in the surface and in the bulk.
• The coercive field increase with increasing the thin film thickness.

The magnetic properties of ferrimagnetic spin-2 and 3/2 Ising-typed thin films are studied by Monte Carlo simulation. The critical temperature is obtained for different values of thickness of the thin film and for different exchange interactions. The total magnetization has been determined for different values of exchange interactions in surface and in bulk and different temperatures. The magnetic hysteresis cycle is obtained for different values of exchange interactions ferro and antiferromagnetic in the surface and in the bulk and for different values of temperatures for a fixed size of the film thickness. The coercive field increase with increasing the film thickness.
