"Effect of Spin-Orbit Interaction on a Magnetic Impurity in the Vicinity of a Surface";
Physical Review Letters,
We propose a new mechanism for surface-induced magnetic anisotropy to explain the thickness
dependence of the Kondo resistivity of thin films of dilute magnetic alloys. The surface anisotropy
energy, generated by spin-orbit coupling on the magnetic impurity itself, is an oscillating function of the
distance d from the surface and decays as 1/d2. Numerical estimates based on simple models suggest that
this mechanism, unlike its alternatives, gives rise to an effect of the desired order of magnitude.
