Multi-Scale Effects of Poling on Structure-Property Relationships in Lead Magnesium Niobate-Lead Titanate Single Crystals
A never-before-seen superlattice in the MPB region was revealed by XRD in the transmission mode. Poling increased the average significance of the superlattice, signifying a structural contribution to the super-structure. The effects of poling on domain and crystallographic structure, and on phase …
