ABSTRACT

Polycrystalline La0.67Ba0.33MnO3 (LBMO) thin film deposited on corning glass (LBMOC)

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%.

Keywords: Magnetoresistance; Thin film
