摘要：

We consider inelastic scattering of localized magnetic moments coupled with the electrons on the surface. We argue that spin-inelastic transitions of the magnetic impurities generate oscillations at a momentum k, corresponding to the inelastic mode, in the second derivative of the current with respect to voltage d(2)I/dV(2). These oscillations are similar in nature to Friedel oscillations. Inelastic Friedel oscillations, which were previously proposed for a spin-unpolarized setup, are here extended for spin-polarized systems. We propose to use scanning tunneling microscopy to measure spin-inelastic scattering generated at the impurity spin by imaging the d(2)I/dV(2) oscillations on the metal surface.
