Resumo

Fe–Ni films were obtained in which the effect of “negative anisotropy” is observed. This effect consists in the formation of easy magnetization axis perpendicular to the deposition field. A model based on negative magnetostriction, and inhomogeneous stresses is tested. The model parameters were varied by applying additional stresses to the film. The effect of additional stresses is analyzed by changing the shape of the R–H curves. It is shown that changes in anisotropy occur in accordance with the model.
