  Perpendicular magnetic anisotropy was found to be highly sensitive to the
nominal thickness and morphology of laterally heterogeneous CoPd films in the
vicinity of the metal insulator transition. We used the effect to tune the
anisotropy by the width of lithographically patterned stripes with non-uniform
cross-sectional thickness profiles. The phenomenon and the method can be
suitable to control the local anisotropy of spintronic logic circuitry elements
by their shape and lateral dimensions.
