XRD and extended x-ray adsorption fine structure measurements indicate larger oblique deposition angle (65 ) leads to more disorder in the Fe crystalline structure. After capping with a Pd overlayer, the Pd/Fe/Al 2 O 3 (0001) still exhibits uniaxial magnetic anisotropy induced by the underlying 1-dimensional Fe nanostructure. This uniaxial magnetic anisotropy changes with the variation in Fe thickness and oblique deposition angle. These results clearly indicate the feasibility of manipulating uniaxial magnetic anisotropy and crystalline order through the oblique deposition of magnetic materials.
