摘要：
In this paper, we report the results about the synthesis and characterization of optimally doped La0.85Na0.15MnO3 thin films deposited onto SrTiO3 (100), NdGaO3 (100) and NdGaO3 (110) for thickness ranging from 11 to 82 nm. The effect of the substrate nature and orientation and film thickness was investigated in order to optimize the physical properties of the films. We obtained very smooth films displaying magnetoresistance values greater than 70% for temperature near to room temperature which makes them appealing for applicative purposes.
