摘要：

We have investigated the various phase boundaries in the (x,T) phase diagram of the solid solution Rb1-x(ND4)xD2PO4 by means of the non local NMR probe Rb-87. Clear evidence for soft-mode behavior was found for the phase transitions to the long-range-ordered ferroelectric (x = 0.15) and antiferroelectric (x = 0.95) phases, whereas thermally activated behavior was observed for the deuteron glass composition x = 0.50. However, the composition x = 0.70 exhibits a diffuse phase transition to ''long-range'' antiferroelectric order and a ''relaxor'' type dynamics.
