Microstructure and magnetoresistance of a La0.67Ca0.33MnO3 film produced using the dip-coating method

The microstructure and magnetoresistance properties of polycrystalline bulk La0.67Ca0.33MnO3 and a La0.67Ca0.33MnO3 film produced on a LaAlO3 (100) single-crystal substrate using the dip-coating method were investigated. X-ray powder diffraction indicated that both film and bulk samples have perovsk...

Description
Summary:The microstructure and magnetoresistance properties of polycrystalline bulk La0.67Ca0.33MnO3 and a La0.67Ca0.33MnO3 film produced on a LaAlO3 (100) single-crystal substrate using the dip-coating method were investigated. X-ray powder diffraction indicated that both film and bulk samples have perovskite structure. Scanning electron microscope and X-ray results clearly indicated that a La0.67Ca0.33MnO3 film was successfully produced using the dip-coating process. This film showed a metal-insulator transition at 269K and a maximum magnetoresistance ratio (MR (%)) of 56% at 269K and 6T magnetic field.
