DOIAbstract
Mössbauer and other studies establish that in La<SUB>1−x</SUB>Sr<SUB>x</SUB>CoO<SUB>3</SUB> (x>0.125), ferromagnetic Sr<SUP>2+</SUP>-rich clusters coexist with paramagnetic La<SUP>3+</SUP>-rich regions in the same crystallographic phase, with the ferromagnetic component increasing with increasing x and decreasing T. The 3d holes created by Sr<SUP>2+</SUP> substitution are itinerant both above and below T<SUB>C</SUB>. All the experimental observations on this system can be explained on the basis of itinerant-electron ferromagnetism
