  We demonstrate that electronic transport through single molecules or
molecular ensembles, commonly based on gold (Au) electrodes, can be extended to
superconducting electrodes by combining gold with molybdenum-rhenium (MoRe).
This combination induces proximity-effect superconductivity in the gold to
temperatures of at least 4.6 Kelvin and magnetic fields of 6 Tesla, improving
on previously reported aluminum based superconducting nanojunctions. As a proof
of concept, we show three-terminal superconductive transport measurements
through an individual Fe$_4$ single-molecule magnet.
