Abstract

The structure of Co/Pd multilayers has a strong effect on the localized anisotropy distribution within a film and the resulting switching properties of nanostructures fabricated from identical material. By varying the underlying seed layer, the microstructure can be controlled from being highly (111) textured to having a random grain orientation. We find a strong correlation between the lateral homogeneity of grain orientations and the localized anisotropy distribution in the material. X-ray diffraction and reflectivity indicate that the interface is better defined and more uniform in the textured case, consistent with the presence of a strong interface-like anisotropy.
