Abstract :
Polycrystalline and epitaxial La0.7Sr0.3MnO3 (LSMO) thin films are fabricated by chemical solution deposition (CSD) method on Si (1 0 0) and LaAlO3 (1 0 0) single crystal substrates, respectively. The transport and magnetic properties of the films are investigated. The magnetoresistance (MR) of LSMO films fabricated on Si (1 0 0) substrates is largely enhanced at low temperatures compared with that of LSMO films on LaAlO3 substrates. The difference of MR properties is discussed in terms of grain boundary (GB) effects.
