“…The low-field magnetic absorption is more pronounced for La 0.9 Sr 0.1 CoO 3 . In accordance with the EPR studies on La 1Àx Sr x CoO 3 [22,26,37], the broad signal and the low-field magnetic absorption can be assigned to ferromagnetic Co 3+ -Co 4+ clusters and spin glass behaviours, respectively.…”

“…We have to mention that at T4300 K two overlapping EPR signals with g % 2:3 have been detected for La 0.9 Sr 0.1 CoO 3 obtained by the sol-gel method at 1000 1C [22]. These signals have been attributed to paramagnetic oxygen species and to species involving cobalt (such as Co 3+ /O 2 À pairs) [22]. These signals are not detected for pure and Sr-doped LaCoO 3 samples studied by us.…”
