(a) MOKE hysteresis loops of 2-nm Pd/3-nm Fe measured at different azimuthal angle φ. (b) Polar illustration of the magnetic remanence (M r )/magnetic saturation (M s ) ratio (i.e., squareness of hysteresis loop). Despite the 4-fold symmetry in the crystalline structure of Fe(001), the azimuthal angular dependent magnetic behavior indicates the dominance of a uniaxial magnetic anisotropy.
