BiFeO3 is recognized as promising candidate because of its potential applications in the design of devices combining magnetic, electronic, and optical functionalities. Connection to this pure and Ni & Ti doped BFO thin films were successfully deposited on FTO substrate using hot wall assisted spray pyrolysis system. The structural, morphological and optical properties of thin films were discussed well. The films structure were confirmed with XRD diffraction pattern, and it observed that the samples are polycrystalline in nature and the observed diffraction peaks are indexed to rhombohedral...
