文摘
- •
La0.7−xSmxBa0.3MnO3 (0≤x≤0.2) synthesized via a solid state reaction route.
- •
Rietveld refinements of high quality powder XRD show good convergences.
- •
Samples show the high magnetoresistance in broad temperature range.
- •
Thermopower study shows that all samples exhibits small poloran hopping mechanism.
