在（1-x）Pb（Fe 2/3W 1/3）O3-xPb（Co 1/2/W 1/2）O3体系中形成了完全固溶体。测量了该体系的晶体学、介电、磁性和穆斯堡尔谱。结果表明，在0.1 ≤ × ≤ 0.7范围内的化合物为铁电-亚铁磁体，具有Fe~（3+）、Co~（2+）和W~（6+）离子的有序排列。提出了介电和磁相图。根据Goodenough等人和Gilleo的假设，讨论了该系统和磁居里温度或Neel温度随组成的变化。用我们提出的模型讨论了穆斯堡尔谱的形状。
Complete solid solutions were formed in the system of (1 - x)Pb(Fe2/3W1/3)O3-xPb(Co1/2/W1/2)O3. Crystallo-graphic, dielectric, magnetic properties and Mossbauer spectra were measured for the system. It was concluded from our measurements that the compounds in the range of 0.1 ≤ × ≤ 0.7 are ferroelectric-ferrimagnets, having the ordered arrangement of Fe3+, Co2+ and W6+ ions. Both dielectric and magnetic phase diagrams were proposed. The system and the variation of the magnetic Curie or Neel temperature, with the composition, was discussed, based on the hypotheses of Goodenough et al. and Gilleo. The shapes of the Mossbauer spectra were also discussed using our proposed model.
