Abstract
Results on Structural, Electric, Thermoelectric power, and br Magnetic properties of a series of Li doped lanthanum manganites, br La1-xLixMnO3 (0.05 ≤ x ≤ 0.30 at.%) have been presented and br discussed. The samples were polycrystalline ceramics prepared by br conventional solid state reaction method. Elemental analysis showed br the variation in composition causes significant morphological br changes. Commonly the grain size decreases with increasing lithium br content (except at x = 0.10 at.%)
