Molecular QuantumSpintronic Devices based on Spin Transition Complexes and Single Molecule Magnets

<strong>Seminar of the School of Physical Sciences -------------------------------------------------</strong> Title: <strong>Molecular QuantumSpintronic Devices based on Spin Transition Complexes and Single Molecule Magnets</strong> Speaker: <strong>Mario Ruben</strong> (Institute for Nanotechnology, KIT, Karlsruhe and IPCMS, Université de Strasbourg, Strasbourg) Date:<strong> August 26, 2015</strong> <strong>Abstract: </strong>Magnetic molecules have recently attracted interest in view of their potential to realize nanometre-sized (single-)molecular spintronic devices by a combination of bottom-up self-assembly and top-down lithography techniques. We report herein on the controlled generation of magnetic molecular nanostructures on conducting surfaces, partially self-assembled on sp2-carbon nano-structures (SW-CNTs, graphene, etc.), or between nano-gap gold electrodes. The obtained supramolecular devices are investigated in view of their I-V-characteristics by means of UHV- and solution-based scanning probe, break junction and electromigration techniques.
