Probing transverse magnetic anisotropy by electronic transport through a single-molecule magnet

By means of electronic transport, we study the transverse magnetic anisotropy of an individual Fe4 singlemolecule magnet (SMM) embedded in a three-terminal junction. In particular, we determine in situ the transverse anisotropy of the molecule from the pronounced intensity modulations of the linear conductance, which are observed as a function...

Manipulation of organic polyradicals in a single-molecule transistor

Inspired by cotunneling spectroscopy of spin-states in a single OPE5-based molecule, we investigate the prospects for electric control of magnetism in purely organic molecules contacted in a three-terminal geometry. Using the gate electrode, the molecule is reversibly switched between three different redox states, with magnetic spectra revealing...
