Inelastic Neutron Scattering on Cobalt Single Molecule Magnets
For the characterization of single molecule magnets (SMMs), insight into their magnetic structure is crucial. The magnetic anisotropy of an SMM is determined by the splitting of the electronic ground state due to zero-field splitting (ZFS). For an in-depth characterization, it is necessary to know the magnitude of the ZFS, which can be >>10 meV. An excellent tool is inelastic neutron scattering (INS). Additionally, a characterization of the phonon states of the SMM is feasible with INS. INS is also superior to EPR spectroscopy, as transitions with ¿S=±1 are allowed, a fact that will be crucial for the understanding of the electronic structure of the Co SMM, we are working on. In the current study, we propose to investigate a tetrahedral Co(II) SMM by INS. In far infrared (FIR) spectra at various magnetic fields of the complex, a field dependent feature at 28 meV is found, which can be assigned to the transition between the two zero-field split Kramers doublets of the S=3/2 state. Also, strong signatures of substantial spin-phonon coupling are observed. Here, INS measurements at max. two temperatures may help elucidating the nature of the field dependent features in the FIR-spectra.
