Abstract

The combined local structure techniques, extended x-ray absorption fine structure and neutron pair distribution function analysis, have been used for temperatures 4≤T≤330K to rule out a large Jahn-Teller (JT) distortion of the Co-O bond in La1-xSrxCoO3 for a significant fraction of Co sites (x≤0.35), indicating few, if any, JT-active, singly occupied eg Co sites exist.
