The local atomic structure and phonons in Ba0.5Sr0.5TiO3
TL;DR: The study of the local atomic structure of the solid solution of Ba0.5Sr0.4TiO3 (BST) has shown that its microscopic properties are quite distinct from those of the end members of the series as discussed by the authors.
Journal ArticleDOI
Observation and mobility study of single 180° domain wall using a near-field scanning optical microscope
TL;DR: In this article, the polarization rotation of a linear polarized laser beam due to the birefringence at the domain wall was measured with 80-100nm spatial resolution using a collection mode Near Field Scanning Optical Microscope.
Journal ArticleDOI
Ferroelectric domain kinetics in congruent LiTaO3
Venkatraman Gopalan,Amit Vasant Itagi,S. Gerstl,Pieter J. Swart,Q. X. Jia,Terence E. Mitchell,Tuviah E. Schlesinger,Daniel D. Stancil +7 more
TL;DR: In this paper, the authors present real-time studies of nucleation and growth of 180° ferroelectric domains in congruent LiTaO3 under an external electric field using optical microscopy.
Proceedings ArticleDOI
Evolution of microstructure in displacive phase transformations
TL;DR: In this article, the authors describe the behavior of simple dynamical models of shape-memory alloys which display the formation of microstructure and the effects of viscoelastic damping on the stability of steady state solutions, the propagation of phase boundaries, and the long-time approach to minimum energy states.
