MONTE-CARLO APPROACH FOR F-AF COUPLING LAYERS

A novel approach using the Monte Carlo method and the more realistic s pin model of ferro and antiferromagnetic exchange coupling layers has been performed. The results obtained confirm and are comparable to exp erimental results and give numerical background to previous theories. The feature of our results is two type of oscillational decay of avera ged antiferromagnetic spin directions every atomic plane in (111) and (100) crystalline orientation. Such a behavior suggests different exch ange anisotropies and their thickness dependencies in the each crystal line orientation.
