| description | Comparative study of magnetotransport and magnetic properties in strong magnetic fields up to 47 T is reported for nanocrystalline and polycrystalline mixed valence manganites La0.8Sr0.2MnO3. The low temperature resistivity enhancement observed only in nanocrystalline manganite is ascribed to the electrostatic blockade of charge carriers between the fine grains/crystallites. Small polaron model is found to describe the high temperature conductivity both in poly- and nanocrystalline manganites. The quantitative analysis supplies the low temperature blocking energy barrier and polaron activation energy. An evolution of resistivity with temperature and magnetic field reveals the intrinsic and extrinsic contributions to large negative magnetoresistance effect. The magnetoresistance is found to be correlated with a squared magnetization. |
