Ferroelectricity of highly preferentially oriented (BiFeO3)1−x –(BaTiO3) x solid solution film by sol–gel method

A new solid solution, (1−x)Bi0.5Na0.5TiO3+xBaCoO3−δ materials, was fabricated using the sol–gel method. X-ray diffraction showed that the crystal structure of the compound exhibited rhombohedral symmetry and is similar to the crystal structures of host Bi0.5Na0.5TiO3 materials. Distortions in the structures and reduction in the optical band gaps of the Bi0.5Na0.5TiO3 materials were possibly due to the random incorporation of Ba and Co cations into host lattice materials. The magnetic properties of the Bi0.5Na0.5TiO3 materials were tuned by controlling the concentrations of BaCoO3−δ as the solid solution. We expect that our work will provide valuable information on current methods for integrating ferromagnetic properties into lead-free ferroelectric materials for the development of multiferroic materials.

The Impact

A modified sol-gel method using metal nitrate salts was adopted to synthesis proton conductor of Ba(Ce1-xZrx)0.95Yb0.05O2.975 where x=0.2, 0.3, 0.4, 0.5 and 0.6 ceramic powders. The aim of this work is to study the crystal structure of Yb-doped barium cerate solid solution at different Zr concentrations. The powder was calcined at 1100°C for 12 hours and pressed at 5 tons to become a pellet by a dry pressing technique. The pellet was sintered at 1400°C in air for 6 hours and ground to powder form prior to the X-ray diffraction measurement. The raw diffraction data of the sample at room temperature was analyzed using Rietveld refinement method in X’pert Highscore software. Cubic crystal structure was observed by software with goodness of fit in average 2.82. Phase formation, structure analysis and the empirical rule which holds the linear relation between lattice parameters at different Zr concentrations using Vegard’s Law were also presented and discussed.

Synthesis of BiFeO3-BaFe12O19 solid solution is aimed to enhanced magnetic properties of the material which can improve the quality of multiferroic properties of material. As we know that BiFeO3 is a multiferroic material if it is in single phase but unfortunately it is difficult to produce BiFeO3 in single phase, which can cause a large current leakage arising from non stoichiometric. It used sol gel method to produce BiFeO3-BaFe12O19 solid solution with weight ratio of 1;1. To know magnetic properties, it was used permagraph test which is type of MPS magnet â€“ Physic EP3 â€“ Permagraph L . The sintering temperature was 750, 800 and 850oC for 8, 10 and 12 hours respectively. There is no regularity in increasing and decreasing of remanent and coersivity properties with increasing sinter temperatures and time of sintering but there is an increasing magnetic energy with increasing sinter temperatures and time of sintering. The highest value of magnetic energy, 10.716 GkA/mÂ belongs to powder sintered at 850oC for 12 hours.
