Abstract :
An approach using the Monte Carlo method and the more realistic spin model of ferro and antiferromagnetic exchange coupling layers has been performed. The results obtained confirm and are comparable to experimental results and give numerical background to previous theories. A feature of the results is two types of oscillational decay of averaged antiferromagnetic spin directions in every atomic plane in (111) and (100) crystalline orientation. Such a behaviour suggests different exchange anisotropies and their thickness dependencies in each crystalline orientation
