Abstract
Nuclear spin resonance has been used to study the deuteron magnetizati on recovery in (KI)0.5(ND4I)0.5 mixed crystals. At high temperatures t he spin-lattice-relaxation is exponential. For T less than or similar to 45 K deviations from this simple behaviour occur, signalling the on set of spatial inhomogeneities due to the formation of an orientationa l glass. The results demonstrate that the transition of (KI)0.5(ND4I)0 .5 into the glassy state is driven by the freezing of random bonds.
