| Low Temperature Isotope Effect in Ammonium Hexachloroselenate(IV) Studied by 35C1 NQR  | | | | Abstract
| The temperature dependence o f the 35C1 N Q R frequency and spin-lattice relaxation time TlQ of (N H 4)2SeCl6 and (N D 4)2SeCl6 were measured from 400 K to 24.8 and 53.8 K, respectively. The disappearance of N Q R signals in the low temperature region of both salts is attributed to phase transitions. We concluded from the temperature behavior of just above the transition point that the operative mechanism o f the transition is different in these salts: The transition of (N D 4)2SeCl6 seems to be associated with rotary soft modes, while in the natural salt non-rotary soft modes seem to play an important role at the transition. | | | |
