Microstructure and Structure of LaMnO₃/Mn₂O₃ Film Prepared by Electrodeposition Method

In this study, LaMnO₃/Mn₂O₃ (LMO/MO) film are synthesized using electrodeposition method on SS 316L substrate. The preparation LMO/MO for this electrodeposition was carried out with a concentration of La³⁺ and Mn²⁺ between 50-150 mM solution. Electrodeposition results show that with a currents variation of 0.1; 0.5; 1; 2.5 mA, LaMnOH_x and MnOH_x compounds have been formed. It is also observed that an increasing current are followed by increasing in the composition of the La atom. The good thickness of sample occurs at currents of 1 mA. The sample was then heated at 800°C for 4 hours. The X-ray diffraction (XRD) analysis shows that the sample forms LaMnO₃ and Mn₂O₃ phase with ratio composition of 1.79% and 98.21%.
