Magnetic molecules for electronic devices is the main part of the emerging research field known as Spintronics. In order to build up such devices, the molecules are deposited on metallic surfaces to have a monolayer. Thus, the molecules are easily accessible to a second electrode, for instance the tip of an STM microscope or also to build devices using fixed-electrodes breakjunction techniques. These magnetic properties can also be calculated and also the conductance through magnetic molecules using DFT methods combined with non-equilibrium Green Functions. In our group, we are using Green function methods to study the transport properties and simultaneously performing STM experiments to measure the conductance at the single-molecule level.
