title: Dynamic hydrogen disorder in yttrium-dihydride phases as seen by variable-temperature 89Y CP MAS NMR.
abstract: Variable-temperature solid-state MAS NMR studies on some yttrium-dihydride phases YH2+x are reported and yield evidence that 89Y CP MAS NMR techniques are an experimentally feasible route to investigate order-disorder phenomena in such metal-hydride phases.
