Description
Endofullerenes are candidate systems for molecular spintronics and electronics. Ho3N@C80 has been studied using x-ray absorption spectroscopy (XAS) at different temperatures with a low noise Everthart-Thornley detector at the PEARL beamline of the Swiss Light Source. Molecules were air-brushed on a graphene substrate, then introduced into vacuum and annealed. X-ray photoelectron spectroscopy indicates a monolayer of molecules. XAS at the Ho M45 edge is performed at different temperatures with per mille accuracy. Multiplet theory predicts the spectra as a function of the orientation of the plane spanned by the three Ho atoms in the molecules.
