Abstract

We designed and fabricated highly textured Bi₅Ti₃Fe_1-_xCo_xO₁₅ (BTFCO-x; x = 0.1, 0.2, 0.3 and 0.4) ceramics by a template grain growth (TGG) method. The textured BTFCO ceramics show the enhanced ferroelectric properties with typical ferromagnetism at room temperature. The remanent polarization (P_r) and remanent magnetization (M_r) are 19.0 μC/cm² and 107.5 memu/g, respectively. The textured BTFCO ceramics process the largest piezoelectric coefficient d₃₃ of 36.8 pC/N. Compared with pure Bi₅Ti₃FeO₁₅ (BTFO) ceramics, the textured BTFCO ceramics exhibit no significant decrease in ferroelectric Curie temperature (T_C∼750 °C). The texturization technology and Co element modification provide feasible methods to improve the multiferroic properties of BTFO-based ceramics and demonstrate the possibility for practical applications.
