Grain morphology and size disorder effect on the transport and magnetotransport in Sol-Gel grown nanostructured manganites

► Single phasic nanostructured manganites can be synthesized at low temperatures. ► Sol-Gel technique is low cost, simple and easy to handle. ► Grain morphology modifies the transport and magnetotransport properties. ► Surface contribution to the modifications in the transport and MR behavior. ► Interplay between low temperature extrinsic and room temperature intrinsic MR.
