“…At 900 • C, all studied LaCoO 3 samples studied exhibited the identical lattice parameters, which coincide with those for LaCoO 3 reported in the literature [47,48]. The organic components of the precursors affect the oxi- [34,38,39,49]. Thus, for LaCoO 3 prepared from freeze-dried citrates with a La:Co:CA ratio of 1:1:2, defects including ferromagnetic coupled Co 3+ and Co 4+ ions were detected by EPR [34].…”
