BiFeO3is a multiferroic substance whichexhibitsboth antiferromagnetic and ferroelectric behaviour.Manganese doped Bismuth ferrite (BiFeO3) nanoparticles were preparedby usingco-precipitation method,BiFeO3 was fabricated with the substitutionof manganese from 10%, 20%, 30%,40% and50%.However, asmall lattice distortion or phase change appeareddue to shifting of peaks to the higher angle in bismuth ferritesamples, it also enhances the Mn content. Thecrystal structure, average crystallite size, hkl planes, lattice constant and volume of unit cell were analyzed by using XRD.We demonstrate that the valueof lattice constant“a” increased while volume ofunit cell gradually decreases, however,average crystallite size changed irregularly. Results accomplished by SEMare illustrated toobserve thechange incompositionof the samples by variation of manganeseconcentration.The optical characteristics of the prepared specimen have been measured using UV-Vis spectroscopy.The wavelength range of absorptionspectrumisfound in between 378nmto 385nm. The magnitude of I − V curve gradually decreases on further increment of dopant elemen.
