Abstract	The code is developed for the calculation of the magneto-crystalline anisotropy (MAE) in thin films using a classical Heisenberg hamiltonian with a correction developed by Van Vleck. A Metropolis style Monte Carlo algorithm was used with adequate corrections to accelerate the calculation. The MAE was calculated for the case of a thin film with an increasing number of defects on the top layer for the cases where the defects were distributed randomly and when they assumed ordered positions. The results obtained agree qualitatively with the results provided by the literature and with the theory.
