TDPAC study of stoichiometric and reduced MoO3 localization of indium-trapped oxygen single vacancies

The time‐differential perturbed angular‐correlation technique is applied to study stoichiometric and reduced molybdenum trioxides. Hyperfine characterization of 111Cd‐probes substitutionally replacing Mo in the perfect crystalline lattice is presented. The trapping of doubly ionized oxygen vacancies...

Zusammenfassung:	The time‐differential perturbed angular‐correlation technique is applied to study stoichiometric and reduced molybdenum trioxides. Hyperfine characterization of 111Cd‐probes substitutionally replacing Mo in the perfect crystalline lattice is presented. The trapping of doubly ionized oxygen vacancies in the most weakly bond site of the cation next neighbour is revealed by measurements in reduced MoO3. La méthode de corrélations angulaires perturbées differentielles en temps est untilisée dans l'étude du trioxide de molybdenum. L'interaction hyperfine du 111Cd remplacant substitutionnellement du Mo dans le réseau parfait est characterisée. Les mesures faites dans des échantillons a haut densitée de défauts ont montré l'attrappement de vacances d'oxygene doublement ionisées dans le site moins lié des proches voisins du cation.
