Magnetic properties in the single molecular magnet TbPc2 insulating ferromagnet EuO2 system.

TbPc2 molecules are single molecular magnets (SMM) considered as of possible Qubis realizations in future quantum computing technology and for spinterfaces, spin filtering systems in semiconductors. Metallic substrates are well studied for these molecules but destroy most of the SMM properties. Insulating substrates like MgO are better suited for this purpose revealing coercive fields up to 2 T. Here we will investigate a ferromagnetic semiconducting surface, EuO. This surface is relatively stable in UHV conditions and will be prepared on-site. The magnetic properties of TbPc2 will be investigated on top of this surface.
