Magnetic anisotropies of Ni(111) films on Re(0001) and Fe(110) films on W(110) were analyzed using torsion oscillating magnetometry in UHV. They can be decomposed in volume contributions that are independent of thickness and surface state and can be explained as a superposition of shape, magnetocrystalline and residual strain anisotropies, and surface contributions, which scale with 1/d and depend sensitively on the state of the surface. Néel’s phenomenological anisotropy model provides a useful connection between different components of surface anisotropies.
