N2 - We present a theory for spin-polarized scanning tunneling microscopy (SPSTM) of a Kondo impurity on an unpolarized metallic substrate. The spin polarization of the SPSTM breaks the spin symmetry of the Kondo system, similar to an applied magnetic field, leading to a splitting of the Abrikosov-Suhl-Kondo resonance. The amount of splitting is controlled by the strength of the coupling between the impurity and the SPSTM tip and also the overall spin polarization of the SPSTM.
