Abstract The manganite La 0.7 Sr 0.3 MnO 3 (LSMO) films are deposited on various substrates, such as single crystal LaAlO 3 (0 0 1), SrTiO 3 (0 0 1), MgO(0 0 1), SiO 2 /Si(0 0 1) and amorphous quartz, by using a magnetron DC sputtering system. According to the X-ray diffraction patterns, either the c -axis oriented or the polycrystalline LSMO films are obtained as the LSMO films are deposited on these substrates, depending on the lattice mismatch between the LSMO and the substrates. The c -axis… Expand
