Professor Schmidt will investigate proton glass dynamics using                  measurements of the dielectric susceptibility and nuclear                       magnetic resonance techniques at pressures up to 5 kbar and                     temperatures to 4 Kelvin. The proton glass system, Rb1-                         x(NH4)xH2PO4, is a mixed system of a ferroelectric and an                       antiferroelectric.  Substitutions with deuterium or arsenic will                be made for the hydrogen or phosphorous respectively.  The                      competing ferro- and antiferro-electric interactions prevent a                  transition to an ordered phase and lead to glassy behavior as                   evidenced by the dielectric relaxation time.  A Monte-Carlo                     simulation of this system will be carried out.  An interpretation               based on hindered diffusion of thermally generated intrinsic                    defects, as developed by the principal investigator, will be                    applied to the new results.
