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...

Direct Observation of Magnetic Anisotropy in an Individual Fe4 Single-Molecule Magnet

We study three-terminal charge transport through individual Fe4 single-molecule magnets. Magnetic anisotropy of the single molecule is directly observed by introducing a spectroscopic technique based on measuring the position of the degeneracy point as a function of gate voltage and applied magnetic field. A nonlinear field-dependence is...
