Abstract

We report on the results of Perturbed Angular Correlation measurements in polycrystalline (Co1-xInx)1-δO samples (x = 0.04 and 0.8 at.%) using ion-implanted 111In tracers. The temperature and the oxygen activity (adjusted via a CO/CO2 mixture) were chosen in such a way as to be able to observe defect trapping and detrapping in thermal equilibrium. The results are compared with those obtained for (Co1-xInx)1-δO (x= 0.04 at.%) rapidly cooled to 350 K and for CoO.
