Thin films of La 1− x Ca x MnO 3 ( x = 0.3 , 0.51) have been deposited on LaAlO 3 (LAO) and SrTiO 3 (STO) substrates by magnetron sputtering (MS) and pulsed laser deposition (PLD). Lattice strain induced by substrate misfit results in drastic chang

La 0.7 Sr 0.3 MnO 3 (LSMO) films of variable thickness were deposited by magnetron sputtering on a LaAlO 3 (100) substrate. The substrate-film lattice mismatch causes changes in the microstructure and magnetoresistance. The film structure is characte
