Abstract:	The thermal stability of the easy axis orientation in thin Permalloy films was studied. This orientation was measured by two methods, i.e. the magneto-optic Kerr effect and a novel measurement scheme based on magnetoresistive effects. It appeared that even for small temperature changes rotations of the easy axis occured. Together with the commonly observed irreversible rotations (thermal annealing), reversible rotations were also measured. Variation of film composition, substrate layer and different annealing steps were tried to obtain a better understanding of this unexpected behaviour. No well-defined correlation could be established between the varied parameters and thermal behaviour
