"Syntheses of nanocrystalline perovskite phases of the general formula La1-xSrxMnO3+\u03B4 were carried out employing sol\u2013gel technique followed by thermal treatment at 700\u2013900 \u00B0C under oxygen flow. The prepared samples exhibit a rhombohedral structure with space group R3c source in the whole investigated range of composition 0.20x0.45. The studies were aimed at the chemical composition including oxygen stoichiometry and extrinsic properties, i.e. size of the particles, both influencing the resulting structural and magnetic properties. The oxygen stoichiometry was determined by chemical analysis revealing oxygen excess in most of the studied phases. The excess was particularly high for the samples with the smallest crystallites (12\u201328 nm) while comparative bulk materials showed moderate non-stoichiometry." . . "0022-4596" . "AUG" . .
