Abstract
Perovskite ferroelectric single crystals in the (1−x) BiScO 3 -x PbTiO 3 (BSPT) system were grown using a flux method. The Curie temperature of rhombohedral BSPT(43/57) crystals was found to be about 404 °C, with a rhombohedral–tetragonal phase transition temperature (T r−t ) around 350 °C. The coercive field (E c ) was found to be 13.7 kV/cm for 〈001〉-oriented crystals, while the coupling factor k 33 was determined to be ∼90% at room temperature and was nearly temperature independent until 330 °C. High piezoelectric properties together with a high Curie temperature and coercive field make rhombohedral BSPT crystals promising candidates for the next generation of high-performance, high-temperature actuators and transducers.This publication has 14 references indexed in Scilit:
