Development of lead-free multifunctional materials Bi(Co0.45Ti0.45Fe0.10)O3
چکیده انگلیسی
A lead free multiferroic material, Bi(Co0.45Ti0.45Fe0.10)O3 (BCTF45/10) was synthesized by a solid-state reaction route at high temperatures. BCTF45/10 powder was prepared using appropriate raw maretials in oxide powders with methanol medium. As-prepared circular shaped pellets were sintered at 1053 K for 6 h to produce a compact form. Preliminary structural properties and elemental analysis were determined using X-ray diffraction and energy-dispersive X-ray spectroscopy techniques respectively at room temperature. The microstructure or surface morphology of the sintered sample was carried out by using field emission scanning electron microscope (FE-SEM). The XRD analysis shows that the compound exhibits the single-phase of orthorhombic symmetry. The average crystallite size estimated using the Scherrer's technique was found to be 30 nm. The influence of Co and Ti substitution (at Bi and Ti sites of BiFeO3) on some physical and electrical properties of BiFeO3 was examined by using phase sensitive multimeter in a wide frequency and temperature ranges. The magnetic nature of the sample was studied using vibrating sample magnetometer. Study of room temperature magnetic hysteresis loop exhibits the enhanced ferromagnetic characteristic with saturation magnetization of 5.091 emu/g and coercive field of 0.213 kOe respectively. The enhanced magnetic properties highlight various potential applications of Co/Ti doped BCTF45/10 materials.
