dcterms:description
Series ofsingle-phase La1-xSrxMnO3 nanoparticles (x0.25 0.47)with the size of about 50nm was prepared in molten NaNO2. TEM evidenced well dispersed particles that are not interconnected by sintering bridges in contrast to traditional products.Interestingly,some reduction of the perovskite cell volume, particularly at higherSr contents,was detected by XRD.Moreover,reduced magnetization and decreased Curie temperature in comparison to sol–gel samples were observed.Neutron diffraction analysis of the as-prepared nanoparticles and several comparative samples with x=0.37 indicated that the anomalous behavior of studied particles probably originate in the overdoped outer shell.The overdoping might result from both the surface oxygen chemisorption and from an increased Sr concentration in the shell.
