Spin excitations in the valenced delocalized molecular magnet Fe-14
Molecular magnets are finite clusters of metal ions distributed within a crystalline lattice such that their magnetic properties are molecular. Over the last decades such systems have represented ideal test beds to investigate the collective behaviour of unpaired electrons using inelastic neutron scattering. With ILL proposal 4-06-8, the first investigation of the spin dynamics within a molecular magnet exhibiting electron delocalisation due to mixed valency began. With this easy-proposal, we seek to finalize that investigation. The availability of a isotope-enriched sample will allow us to perform higher-resolution measurements with low incoming energy to investigate thermally populated transitions and complete the picture of the spin dynamics in a valence-delocalised molecular magnet.
