Lay Summary (German)

Lead
“Single molecule magnets” zeigen Eigenschaften, wie sie sonst nur in Festkörpern beobachtet werden. Dies ist z.B. Hysterese, d.h. die Moleküle können magnetische Information auf kleinstem Raum speichern. Wenn seltene Erden in Fullerene eingebaut werden, wird die Orientierung ihrer 4f Spins innerhalb der Atome "Matroschka - artig" weiter geschützt was ihre magnetischen Eigenschaften besonders gut macht.
Lay summary

Das Projekt will den "besten" single molecule magnet in der Familie der Nitride Cluster Fullerene suchen und finden. Die Herstellung und Reinigung dieser Moleküle ist langwierig und ihre Familie hat etwa 2000 Mitglieder. Dies bedeutet, dass kleinste Mengen analysiert werden sollten,um die magnetischen Eigenschaften der einzelnen Kandidaten zu erfassen und zu vergleichen. Die Methode der Wahl für die magnetische Analyse ist x-ray magnetic circular dichroism, wie er z.B. an der Swiss Light Source untersucht werden kann.

Abstract

The quest for the ”best” single molecule magnet shall be concerted for the new members, the rare earth (R) containing R3N@C80 nitride cluster endofullerenes. Such carbon cage molecules contain 3 trivalent rare earth ions and one nitrogen anion and may be considered as ”spin shuttles” where the spin of the endohedral unit is protected by a diamagnetic carbon shell. Trimetal nitride cluster endofullerenes are known to be very stable and radiation hard, which allows them to be sublimated and self assembled on surfaces, and investigated with x-rays. Based on a recent breakthrough [Westerstrom et al. (2012) [1]] , where extraordinary long spin relaxation times for DySc2N@C80 have been found, IFW Dresden (D) will synthesize and isolate new nitride cluster fullerenes, and the group at PSI and UZH (CH) will investigate the magnetic properties by means of x-ray circular dichroism and magnetometry, with emphasis on longevity of the orientation of the magnetic moments. Based on the ”educated” feedback of CH, D will synthesize new molecules out of the many possible combinations in the rare earth clusters. The added value for the single molecule magnet community will be the experimental exploration of the new family of molecular magnets, which bears unique properties due to its relative simplicity and tunability of the structural parameters.s for DySc2N@C80 molecules have been found, IFW Dresden (D) will synthesize and isolate new nitride cluster fullerenes, and the group at PSI and UZH (CH) will investigate the magnetic properties by means of x-ray circular dichroism and magnetometry, with emphasis on longevity of the orientation of the magnetic moments.
