Lattice Mode

A new design for a nuclear quadrupolar resonance probe to study solids subjected to high hydrostatic pressures at low temperatures is presented. Measurements of the 35Cl spin-lattice relaxation are reported at three pressures in the temperature range just above the structural phase transition in the antifluorite crystal K2OsCl6. These data are influenced by the softening of the rotary lattice mode and the evolution of a dynamic central peak. A small pressure dependence of the correlated fluctuations associated with the soft mode is observed; however no detectable effect on the correlated fluctuations associated with the dynamic disorder component of the central peak is seen.
