Outline of Final Research Achievements

Lanthanide(III) complexes which show a slow magnetic relaxation phenomenon are called as lanthanide-based single molecule magnets, SMMs. In this work, we have investigated the detail of the spin-flipping process of SMMs by means of the inelastic neutron scattering method. The application of neutron scattering on the soft materials such as SMMs was rather rare, and we have first explored the complexes which show SMM behavior being suitable for such a measurement. After detailed study of magnetic properties of candidates, we have synthesized two samples of which all hydrogen atoms were exchanged with deuterium (C40D39N8O11S2Zn2Ln、>98% atom D), and neutron scattering experiments were carried out at Cold-Neutron Disk-Chopper Spectrometer : AMATERAS, J-PARC, Tokai-mura. The analyses of the scattering data are now ongoing.
