Popis:	The microstructure and dielectric properties of (La0.9Sr0.1)[(Ga1−x Crx)0.8Mg0.2]O3−δ (x = 0−0.35) oxygen-ion-conducting ceramics have been studied. The dielectric relaxation observed in the ceramics has been interpreted in terms of ionic transport in the grain bulk and across grain boundaries. The grains in the ceramics have been shown to consist of nanoscale domains, which seems to be due to a correlated distribution of the chromium dopant.
