Chemical investigation of Fe<sup>3+</sup>/Nb<sup>5+</sup>-doped barium titanate ceramics

Renewed interest in the perovskite ferroelectric barium titanate (BaTiO3) has been driven by the introduction of large recoverable electrostrain in doped BaTiO3-based materials. Our previous work demonstrated that the potential for high-performance in Pb-free ferroelectrics based on BaTiO3was confir...
