Abstract / Bemerkung
We report an Inelastic Neutron Scattering (INS) study of the fully deuterated molecular compound K-6[V-15(IV) As6O42] . 9D(2)O(V-15). Due to geometrical frustration, the essential physics at low temperatures of the V 15 cluster containing 15 coupled V4+ (S = 1/2) is determined by three weakly coupled spin-(1/2) on a triangle. The INS spectra at low energy allow us to directly determine the effective exchange coupling J(0) = 0.211(2) meV within the triangle and the gap 2 = 0.035(2) meV between the two spin-(1/2) doublets of the ground state. Results are discussed in terms of deviations from trigonal symmetry and Dzyaloshinskii-Moriya (DM) interactions.
