The influence of substitution of Co by lithium on the structural, electrical conductivity and magnetic properties of La0.7Ba0.3Co1-xLixO3-delta (x = 0.0 and 0.1) systems was investigated. Samples were prepared by the polymerized complex sol-gel technique and sintered at 900 C for 2 h. Thermal, XRD, and IR studies of the two systems confirm complete solid solution formation and crystallization with cubic perovskite structure. By replacing Co by Li (x = 0.1), the lattice parameter increases, and nanocrystalline particles in the range of 25-90 nm were obtained. The system with Li substitution has a higher electrical conductivity with lower activation energy and has a ferromagnetic behavior in the range of measuring temperatures and magnetic field.
