Abstract:
The effects of lattice distortion on the physical properties of La <sub>0.7</sub>Ca<sub>0.3</sub>MnO<sub>3</sub> and La<sub>0.5</sub>Ca<sub>0.5</sub>CoO<sub>3</sub> films are investigated. Our results suggest that larger substrate-induced lattice distortion gives rise to larger zero-field resistivity and larger negative magnetoresistance.
