B 34 Rapid Commun. 2035-2037 (1986).1098-0121https://scholarworks.montana.edu/handle/1/8960Studies of the frequency-dependent dielectric properties of a Rb0.52(ND4)0.48D2PO4 (72% deuterated) crystal have shown that the deuteron glass-freezing temperature Tg is suppressed by hydrostatic pressure at a rate of -2.0 K/kbar. This is explained in terms of the influence of pressure on the hydrogen-bond potential. It is suggested that the glassy state should be completely suppressed (i.e., Tg→0 K) at a pressure of less than 10 kbar in undeuterated crystals of similar composition.Low temperature physicsMaterials sciencePhysicsArticle
