Abstract
Multiferroic Bismuth Ferrite (BiFeO3 or BFO) is one of the promising lead-free multifunctional materials for device applications. In this work, we fabricate bismuth ferrite and manganese doped bismuth ferrite (BiFe1−xMnxO3, x = 0.1, x = 0.2, up to 20%) nanoparticles by a modified sol-gel processing technique. The variation of dielectric constant () and loss tangent (tanδ) as a function of frequency at room temperature were investigated and ac conductivity was also calculated. The magnetic properties were also investigated and analyzed from vibrating sample magnetometer(VSM) data. The overall magnetic and electrical properties of the BFO ceramic samples were improved with Mn doping.
