The Relation of Local Order to Material Properties in Relaxor Ferroelectrics



Matthew Krogstad, Peter M. Gehring, Stephan Rosenkranz, Raymond Osborn, Feng Ye, Yaohua Liu, Jacob P. C. Ruff, Wenzhi Chen, Justin M. Wozniak, Haosu Luo, O. Chmaissem, Zuo-Guang Ye, Daniel Phelan


Four different forms of local order that give rise to diffuse neutron and x-ray scattering in the relaxor ferroelectric series PMN-xPT are identified via broad, three-dimensional surveys of reciprocal space. Composition and temperature-dependent measurements reveal how the local ordering correlates to dielectric and electromechanical properties as well as long-range polar order.
