Description
Yu Yun and a large team find relaxor ferroelectric behavior in a fully ordered crystal, challenging the usual recipe, in 2026. Relaxors show a dielectric response that shifts with frequency and strong electromechanical coupling, normally blamed on chemical disorder breaking up polar order. Their thin films of PbMg0.5W0.5O3 have long range rocksalt ordering of the metal sites.
Cooling moved the films through paraelectric, antiferroelectric, and ferroelectric phases in sequence. Competition between polar and antipolar phases, squeezed by the substrate, broke long range dipole alignment and produced the relaxation. A new low energy polar phase was also identified. Phase rivalry itself can design relaxor behavior.
