Multiferroic (Bi0.86Sm0.14)(Fe1-xTix)O(3 )ceramics (BFO14Sm100xTi) for x= 0.000, 0.005, and 0.010 were synthesized using solid-state reaction method to investigate the influence of Ti(4+ )doping on their microstructure, dielectric, and ferroelectric behaviors. Scanning electron micrographs reveal that the Ti4+ doping facilitates slow oxygen ion diffusion leading to reduced grain size (2.13, 1.75, and 1.50 mu m for BFO14Sm, BFO14Sm0.5Ti, and BFO14Sm1Ti, respectively). High-resolution synchrotron X-ray diffraction (HR-XRD) analysis and Rietveld refinements confirm the phase coexistence of polar R3c rhombohedral and nonpolar PbZrO3-like Pbam orthorhombic phases. The temperature dependent HR-XRD shows that the Ti4+ ions stabilize phase coexistence up to 250 degrees C. The enhanced dielectric homogeneity and decreased conductivity are caused by Ti4+ substitution, which are attributed to reduction of oxygen vacancies. The improved piezoelectric coefficients (d(33)) and symmetric P-E hysteresis loops of BFO14Sm0.5Ti, and BFO14Sm1Ti indicate enhanced ferroelectric order due to Ti4+ ion doping.
