摘要：
Magnetotransport properties of strained La0.65Ca0.35MnO3 thin films with thickness between 10 and 1000 nm were investigated at temperatures near the metal-insulator transition and in magnetic fields up to 0.7 Tesla. The reduction of the thin film thickness, which in turn produces an increasing epitaxial lattice strain, dramatically increases the "in-plane" magnetic anisotropy and the magnetoresistivity.
