Strong interrelationship between anomalous electric-field induced lattice strain along non-polar direction and domain reorientation in pseudorhombohedral piezoelectric ceramic BiScO3-PbTiO3

摘要

The lattice strain and domain switching behaviour was investigated as afunction of cyclic field and grain orientation for a pseudorhombohedralcomposition of the high Curie point piezoelectric system xBiScO3 - (1-x)PbTiO3(x = 0.40) by in-situ electric field diffraction technique with high energysynchrotron x-rays. Along the field direction, the system exhibts five timelarge strain along 100 as compared to the 111 direction. A one-to-onecorrespondence between the 200 lattice strain and the 111 domain switchingsuggests a strong correlation between the two phenomena.
