Abstract

We report a magnetic response of Au/1,6-hexanedithiol/Au single-molecule junctions at room temperature using a mechanically controllable break junction method. The electrical resistance of the junction was found to increase up to 5.5% under a magnetic field. This phenomenon could originate from the unpaired charge at the Au/S interface.
