The structural and magnetic properties of the mixed valent cobaltites La0.5Sr0.5−xAgxCoO3 (0≤x≤0.15) with perovskite structure have been investigated. X-ray diffraction (XRD) analysis using Rietveld refinement shows that all our samples crystallize in the orthorhombic structure with space group. Although the unit cell volume remains almost constant, the Co–O bond length and...
