Abstract

The conductance through a local nuclear spin precessing in a magnetic field is studied by using the equations-of-motion approach. The characteristics of the conductance is determined by the tunneling matrix and the position of equilibrium chemical potential. We find that the spin-flip coupling between the electrons on the spin site and the leads produces the conductance oscillation. When the spin is precessing in the magnetic field at Larmor frequency (omegaL), the conductance develops the oscillation with the frequency of both omegaL and 2omegaL components, the relative spectrum weight of which can be tuned by the chemical potential and the spin-flip coupling.
