研究了在x∈(0,0.50)范围内不同成分的（1−x） PbFe2/3W1/3O3-xPbTiO3铁质体系的磁性能。弛豫剂PbFe2/3W1/3O3陶瓷在居里温度范围内发现磁滞回线异常，证明了磁介电耦合。在体系中发现了两种类型的超交换磁相互作用和一系列的磁跃迁，这些磁跃迁与Neel温度有关。本研究结果证实了弛豫-铁电体系中磁性能与纳米极序之间关系的假设。
The magnetic properties of the ferroic (1−x)PbFe2/3W1/3O3–xPbTiO3 system with various compositions in the range x∈(0,0.50) were investigated. A magnetodielectric coupling is proved by an anomaly of the magnetic hysteresis loop found in the Curie range of temperatures for the relaxor PbFe2/3W1/3O3 ceramic. Two types of superexchange magnetic interactions and a succession of magnetic transitions with Neel temperatures dependent on the composition were found in the system. The present results confirm the hypothesis of a relationship between the magnetic properties and the nanopolar ordering in the relaxor–ferroelectric system.
