Isotope effect of the superconducting transition temperature in binary Chevrel-phase Mo/sub 6/Se/sub 8/

· Phys. Rev. Lett.; (United States)
Isotope-effect measurements on the binary Chevrel superconductor Mo/sub 6/Se/sub 8/ are reported with either Mo or Se replaced by their isotopes. Within our uncertainty the isotope-effect exponent of T/sub c/ proportional M/sup -beta/ is equal in both cases (..beta../sub Mo/ = 0.27 +- 0.04, ..beta../sub Se/ = 0.27 +- 0.05). We concluded that only modes to which the six Mo and the eight Se atoms contribute about equally are determinng T/sub c/: These are acoustic translational modes of the Mo/sub 6/Se/sub 8/ cluster and its internal optical modes, whereas torsional modes of the cluster must be of minor importance.
