We have studied three-terminal electron transport through an individual single-molecule magnet Fe4. Several fingerprints of high spin and magnetic anisotropy have been observed: the Kondo effect in adjacent charge states in an intermediate coupling regime and zero-field splitting in the regime of a weaker coupling. We also observed spin transitions at energies close to the ones reported for bulk Fe4 crystals. Finally, we have demonstrated electric-field control on the magnetic properties of a single molecule.

Abstract
We have studied three-terminal electron transport through an individual single-molecule magnet Fe4. Several fingerprints of high spin and magnetic anisotropy have been observed: the Kondo effect in adjacent charge states in an intermediate coupling regime and zero-field splitting in the regime of a weaker coupling. We also observed spin transitions at energies close to the ones reported for bulk Fe4 crystals. Finally, we have demonstrated electric-field control on the magnetic properties of a single molecule.
