N2 - Finding reliable methods to exploit molecular degrees of freedom represents an intriguing problem involving the control of new mechanisms at the nanoscale and several technological challenges. Here, we report a novel approach to address a single molecular spin embedded in an electronic circuit. Our devices make use of molecules with well-defined magnetic anisotropy (TbPc2) embedded in nanogapped electrodes obtained by electroburning graphene layers. Such devices work as molecular spin transistors allowing the detection of the Tb spin flip during the sweep of an external magnetic field. The spin readout is made by the molecular quantum dot that, in turns, is driven by an auxiliary gate voltage. In the general context of (spin-)electronics, these results demonstrate that: (1) molecular quantum dots can be used as ultra-sensitive detectors for spin flip detection and (2) the use of graphene electrodes as a platform to contact organometallic molecules is a viable route to design more complex nanoarchitectures.
