✦ Synopsis

Here we report on the subtle changes in structure of BiFeO 3 thin films induced by lanthanum (La) doping and subsequent impact on the film's properties. Bi 1-x La x FeO 3 (BLFO) thin films (x = 0.0 to 0.30) were deposited by the chemical solution deposition method on indium tin oxide coated glass substrates. X-ray diffraction analyses of the films indicate the gradual structural changes in the films from a rhombohedral type towards a cubic like structure as the La content increases, also evident from changes in the lattice parameters and disappearance of peak splitting upon increasing doping. This was also accompanied by an increase in the remanent polarization, dielectric constant, magnetization and a marginal decrease in the leakage current density up to x = 0.20 followed by a reverse trend at higher doping levels.
