Magnetoresistance, Thin filmAbstract
Polycrystalline La0.67Ba0.33MnO3 (LBMO) thin film deposited on corning glass (LBMO C) and fused silica (LBMO-FS) substrate were studied. X-ray diffraction (XRD) pattern revealed that all samples shown hexagonal structure with space group of R-3c. LBMO structure experienced different lattice strain when deposited on different substrate. Compression along c-axis is observed for lower lattice strain. This distortion shifted the metal-insulator transition temperature (Tp) to higher temperature from below 90K to 92K for LBMO-FS. The maximum peak of %MR also observed near Tp which is at 108K (LBMO-FS). The highest %MR observed for LBMO-C was -29.34%.
