The temperature dependence of the perpendicular magnetization has been studied in multilayer Co/Pd films through measurements of the anomalous Hall effect. As the temperature is raised, the perpendicular magnetic moment becomes unstable in a zero field. This effect indicates the possibility of an orientational transition at a temperature between 40 and 400 K, depending on the properties of the films.
