Tunneling through magnetic molecules: what can we learn from the master equation? — •Carsten Timm¹, Florian Elste², and Binhe Wu³ — ¹Technische Universität Dresden, Germany — ²Columbia University, New York, USA — ³Max-Planck-Institut für Physik komplexer Systeme, Dresden, Germany

Progress in molecular spintronics requires an improved understanding of electronic transport through magnetic molecules far from the linear-response regime. For weak hybridization with the electronic leads, the method of choice for the theoretical description is the master equation. A number of effects relevant for spintronics, such as spin blockade and spin amplification, will be reviewed. The master equation also sheds light on the spin dynamics, as will be illustrated by the examples of spin relaxation and the current-noise spectrum.
