Electronic transport through single-molecule magnets by scanning tunneling spectroscopy

ORAL

Abstract

Atomic structure of molecules and electrodes are expected to sensitively influence the properties of molecular spintronics devices. We have studied the transport properties of individual Mn$_{4}$ single-molecule magnets bound to a surface using atomic force and scanning tunneling microscopy at cryogenic temperatures Unlike previous scanning probe microscopy experiments, we are able to continuously tune the density of states of individual molecules using novel device geometries in-situ We will discuss transport properties of single-molecule magnets as a function of their atomic structure, coupling to electrodes and the Fermi levels.
