Sodium-Doped LaMnO3 Thin Films:  Influence of Substrate and Thickness on Physical Properties

In this paper we report the results of the synthesis and characterization of optimally doped La1 - x Na x MnO3 thin films grown on SrTiO3 (100), NdGaO3 (100), and NdGaO3 (110) for thicknesses ranging from 11 to 82 nm. The effect of substrate nature and orientation, film thickness, and annealing proc...

Zusammenfassung:In this paper we report the results of the synthesis and characterization of optimally doped La1 - x Na x MnO3 thin films grown on SrTiO3 (100), NdGaO3 (100), and NdGaO3 (110) for thicknesses ranging from 11 to 82 nm. The effect of substrate nature and orientation, film thickness, and annealing procedure was investigated to optimize their magnetoresistance (MR). We obtained very smooth films displaying MR values greater than 70%, near room temperature.
