Crystal Structural Analyses of Ferrielectric Tetragonal (Bi sub(1/2)Na sub(1/2))TiO sub(3)-7%BaTiO sub(3) Powders and Single Crystals

We have investigated the crystal structure of (Bi sub(1/2)Na sub(1/2))TiO sub(3)-7%BaTiO sub(3) (BNT-7%BT) by high-resolution neutron powder diffraction (NPD) and high-energy synchrotron radiation X-ray diffraction (SR-XRD) analyses. The NPD study revealed that the BNT-7%BT crystals have a single-ph...

Description
Summary:We have investigated the crystal structure of (Bi sub(1/2)Na sub(1/2))TiO sub(3)-7%BaTiO sub(3) (BNT-7%BT) by high-resolution neutron powder diffraction (NPD) and high-energy synchrotron radiation X-ray diffraction (SR-XRD) analyses. The NPD study revealed that the BNT-7%BT crystals have a single-phase tetragonal structure with P4bm symmetry. The crystal structure refined by the Rietveld method was found to be similar to the ferrielectric P4bm phase reported for BNT at a high temperature of 673 K. The SR-XRD analyses for single crystals of BNT-7%BT demonstrated that the P4bm phase remains as a stable phase in the crystals even after a high electric field is applied for poling, which is different from the structural analysis of ceramics by Ma et al. [Phys. Rev. Lett. 109 (2012) 107602].
