Investigation on the effect of Zirconium doping on the structural and electrical properties of BiFe_1-x Zr _x O₃ with x = 0.01, 0.03 and 0.05

Abstract

Multiferroic material was interesting because it has many potential applications in sensors, spintronic devices, actuators, memory devices, microelectronic devices, and convertors. Material multiferroic has two or more primary ferroic properties in the same phase. BiFeO3 is a multiferroic material that has two ferroic properties such as antiferromagnetism and ferroelectricity. BiFe1-xZrxO3 with x = 0.01, 0.03 and 0.05 have been prepared by sol-gel method to study effect structural and electrical properties. X-ray diffraction result shows that all of the samples have a hexagonal structure with space group R3c and lattice parameter, volume, density increased when the concentration of zirconium increased. Zr-substitution caused the dielectric constant decrease when the concentration of Zr increases at a lower frequency.
