The project "Spin shuttles" investigates molecules with unpaired electron spins in view of their performance in
Spin shuttle is a term coined for endofullerene molecules that encage and protect an atom or molecule with an open electron shell. Such molecules are candidates for single molecule magnets and have a great potential as building blocks in molecular spintronics. A single molecule magnet is a single molecule that retains its magnetization direction for a long period of time, i.e. displays hysteresis.
The first single molecule magnet spin shuttle was Dy2ScN@C80.
Our experiments cover magnetic characterization of the electronic ground state with magnetometry and x-ray circular dichroism (XMCD). The structure of the molecules on surfaces is investigated by x-ray photoelectron diffraction (XPD), also with resonant excitation (RXPD) and tunneling microscopy (STM) and spectroscopy (STS).
