Experimental investigation on multiferroic properties of Ti-doped BiFeO3 bulk and nanoparticles

Abstract

Abstract Bismuth ferrite (BiFeO3), an inorganic chemical compound, has added a new dimension to the multiferroic materials research. We previously reported the synthesis routes and improved photocatalytic properties of 10% Ti-doped BiFeO3 (BiFe0.9Ti0.1O3). In this study, we investigated the ferroelectric and ferromagnetism properties of BiFe0.9Ti0.1O3 bulk and nanoparticles and compared them with those of undoped BiFeO3 bulk ceramics. Elemental analysis was conducted to explore the chemical composition in the doped samples. The magnetic characterization and electrical measurements were performed in Vibrating Sample Magnetometer and Ferroelectric Loop Tracer respectively. Magnetization versus applied magnetic field, leakage current density, and polarization versus electric field measurements reveal improved multiferroic properties in Ti-doped bulk and nano samples compared to undoped BiFeO3 bulk.
