Time-dependent transport through a molecular level coupled to a nanomagnet — •Milena Filipovic, Federica Haupt, and Wolfgang Belzig — University of Konstanz, Konstanz, Germany

We study the transport through a single level quantum dot coupled to two leads in the presence of a magnetic field. The magnetic field is coupled to the quantum dot and the leads are treated as noninteracting. We use the Keldysh nonequilibrium Green function technique to derive and analyze the properties of the spin-dependent tunneling current and its linear response to the applied time-dependent magnetic field. We further analyze the transport through the single level quantum dot coupled to a precessing molecular nanomagnet.
