Abstract

Oriented thin films of $La_{0.67}Sr_{0.33}MnO_3$ and $La_{0.67}Ca_{0.33}MnO_3$ were fabricated on a $SrTiO_3(002)$ single crystal substrate by the chemical solution deposition (CSD) process. The CSD grown films have electronic and magnetotransport properties which are comparable to those of films prepared by the pulsed laser technique and to those of the bulk single crystal samples. The magnetoresistance of the films was found to be very similar to those of pulsed laser deposition grown films and they show no contribution of grain boundaries unlike polycrystalline films. The atomic force microscopy study of the roughness and its scaling with length shows that the surfaces of the films are self affine.
