Abstract

A solid solution between polar perovskite oxides BiInO3andBiZn1/2Ti1/2O3with the atomic displacement of Bi3+and B-site (In and Zn1/2Ti1/2)as the origin of spontaneous electric polarization was investigated. Polar orthorhombicto nonpolar orthorhombic transition accompanied by negative thermal expansion(NTE) with constant volume shrinkage was observed forx≤0.3 inBiIn1−xZnx/2Tix/2O3. A relative shift of electrical polarization from A-site Bi3+to B-site ions reduced the transition temperature and enabled NTE in a wide temperaturerange with suppressed temperature hysteresis. In addition, new LiNbO3-type phaseswere found for 0.4≤x≤0.8 with ferroelastic and piezoelectric behaviors, featuring a very high switching strain and demonstratingthe potential for enhanced domain wall mobility.
