Out-of-equilibrium singlet-triplet Kondo effect in a single C_60 quantum dot

Abstract

We have used an electromigration technique to fabricate a ${\mathrm{C}}_{60}$ single-molecule transistor (SMT). Besides describing our electromigration procedure, we focus and present an experimental study of a single molecule quantum dot containing an even number of electrons, revealing, for two different samples, a clear out-of-equilibrium Kondo effect. Low temperature magneto-transport studies are provided, which demonstrates a Zeeman splitting of the finite bias anomaly.
