Abstract
Study of structural, magnetic and transport properties of the polycrystalline La0.8Pb0.1 square 0.1MnO3 (LPMO) and La0.8Pb0.1Na0.1MnO3 (LPNMO) samples has been carried out.Finally, wes how that the magnitude of the magnetic inhomogeneity depends on the random substitution in the A-site cations.
