We study the structural and magnetic properties of La{sub 0.7}Sr{sub 0.3}Mn{sub 1-x}Co{sub x}O{sub 3} (0 ≤ x ≤ 1). Rietveld refinement of X-ray Diffraction (XRD) pattern suggests phase purity of the polycrystalline samples with R-3c space group. Interplay of Ferromagnetic (FM) and Antiferromagnetic (AFM) interaction upon Co substitution at Mn site in La{sub 0.7}Sr{sub 0.3}MnO{sub 3} is evident from magnetic measurements. There is an optimal cobalt substitution at which the coercive field is maximum.
