Low-Temperature Synthesis of Ultrafine La_0.7Sr_0.3MnO₃Powder via Chelate Homogenization

Low-field magnetoresistance of La0.7Sr0.3MnO3 nanoceramics processed by different precursor approaches and powder compaction techniques

“…By both procedures we obtained solid foams, which were then heat-treated at 700 °C (oxygen atmosphere, 10 h) to form phase-pure perovskitelike LSMO, as established by X-ray diffraction (XRD). 12 The resultant powders were compacted into pellets, which were air-annealed at 700, 800, 900, 1000 and 1100 °C for 15 h to produce ceramics with different grain sizes.…”
