摘要：
The properties of La1−xSrxCoO3 (x = 0, 0.15, 0.20, 0.30) solid solutions are investigated using neutron diffraction, positive-muon spin relaxation (precession) measurements, and extended X-ray absorption fine structure (EXAFS) and X-ray absorption near-edge structure (XANES) spectroscopy. The results obtained are interpreted within the model of phase separation into ferromagnetic regions enriched with Sr2+ ions and nonmagnetic regions similar in composition to the LaCoO3 compound.
