We report on the growth of Bi1-xLaxFeO3 (BLFO) thin films on quartz substrate using pulsed laser deposition (PLD) technique. The effect of varying La substitution on structural, optical and magnetic properties of BLFO thin films has been systematically investigated. X-ray diffraction (XRD) studies indicate rhombohedral structure of the (BLFO) films along highly oriented (011) peak. The crystallite size was found to increase with increase in La doping. The films show an average transmission of 80 % in the range of 200 – 2000 nm. The La doping in BiFeO3 (BFO) affects the refractive index and optical bandgap. Magnetic studies reveal an enhancement in coercivity, remanent magnetization and susceptibility of the pure BFO films with La doping. The present study elucidates the effect of La doping on various properties of BFO films and that the optical behavior of BLFO films provide a reference for preliminary research to infrared detectors and optoelectronic devices.
