TL;DR

This paper uses Monte Carlo simulations to investigate phase transitions in coupled ferromagnetic-antiferromagnetic bilayer films, revealing that transition temperatures depend on film thickness and occur at different temperatures.

Contribution

It provides new insights into how film thickness influences phase transition temperatures in FM/AFM bilayers through detailed Monte Carlo simulations.

Findings

Phase transitions occur at different temperatures for each film.

Transition temperatures depend on film thickness.

Indications of phase transitions in coupled FM/AFM films.

Abstract

Monte Carlo simulations have been used to study phase transitions on coupled anisotropic ferro/antiferromagnetic (FM/AFM) films of classical Heisenberg spins. We consider films of different thicknesses, with fully compensated exchange across the FM/AFM interface. We find indications of a phase transition on each film, occuring at different temperatures. It appears that both transition temperatures depend on the film thickness.
