초록
We witnessed the enhancement of mangetoresistance (MR) in La0.75Ca0.25MnO3 thin films grown on Si (100) substrates by RF magnetron sputtering. The films are polycrystalline with (100) and (110) orientations. The lattice constants of films are reduced as much as 0.9% compared to the one of the bulk sample, which proves that the compressive stress on films was imposed by Si sbustrate. It is found that the MR value (Δ
