摘要：

Solid solutions between the relaxor ferroelectric Pb3MgNb2O9 (PMN) and the ordered antiferroelectric Pb2MgWO6 (PMW) were studied. X‐ray diffraction shows that the superstructure reflections characteristic of the doubling of the perovskite subcell evident in pure PMW begin to appear in compositions containing more than 20 mol% PMW. Dielectric measurements, however, show that the diffuse transition behavior characteristic of PMN persists up to compositions Containing 80 mol% PMW. Results are discussed on the basis of present models for ferroelectric relaxor behavior. Copyright © 1979, Wiley Blackwell. All rights reserved
