Structural, Morphological and Ferroelectric Properties of Dy doped 0.80BiFeO3–0.20PbTiO3 solid solution

The solid state reaction technique was used to synthesize Dy modified BiFeO3-PbTiO3, i.e. 0.80Bi1-xDyxFeO3-0.20PbTiO3 solid solution with x = 0.05 and 0.10 compositions. The rhombohedral to tetragonal phase transition of solid solutions was observed by the structural analysis based on X-ray diffraction (XRD) analysis. SEM micrographs revealed a dense microstructure with non-uniform grains, altering the ferroelectric characteristics of these solid solutions, and grain size decreases as Dy doping rises. Ferroelectric properties of the compounds are confirmed by electric field dependent polarization (PE-hysteresis) loops. The ability of samples for various electronics device applications may be related to ferroelectric loops with increased remnant polarization with increase in Dy doping.
