英文摘要	Here we report the structural, dielectric, ferroelectric, piezoelectric, and magnetic properties of zirconium-doped 0.67BiFe0.97Ga0.03O3–0.33BaZrxTi1−xO3(BFG–BZT) lead-free ceramics. Structural investigations reveal that the doped Zr4+ions (up to x = 0.15) can be fully incorporated into the host lattice. Dielectric measurements demonstrate that with increasing Zr4+content, both the ferroelectric Curie temperature TCand the dielectric constant decrease monotonously, and that the dielectric constant exhibits relaxor behaviors upon Zr4+doping. At the same time, the remnant polarization Princreases and then decreases, with the maximum Pr∼ 26 µC/cm2for x = 0.025. One of the noteworthy results is that the remanent magnetic moment at room temperature increases up to 0.17 emu/g with increasing x from 0 to 0.15, which is attributed to enhanced lattice distortions due to Zr4+doping. The coexistence of strong ferroelectricity and ferromagnetism at room temperature implies that the BFG–BZT could be potential candidate materials for multiferroic device applications. © 2017, Springer Science+Business Media New York.
