Abstract

In this work, high-quality Mn-doped 0.935Bi0.5Na0.5TiO3–0.065BaTiO3 (Mn-BNBT) ferroelectric film was prepared on the SrRuO3-buffered (100)-oriented SrTiO3 single-crystal substrate using pulsed laser deposition method. The phase structure, morphology, domain and electrical properties were studied. Large remnant polarization Pr up to 35 μC/cm2, moderate dielectric constant ɛT33/ɛ0 of 800 and low dielectric loss tanδ of 0.037 at 1 kHz was obtained at room temperature along with excellent local piezoelectric response. The temperature dependence of the ferroelectric hysteresis loop measurements indicates the ferroelectric long-range order can be sustain as high as 150 °C. The excellent global properties make the present Mn-BNBT thin film quite potential in environmental-friendly piezoelectric integrated device applications.
