摘要：
Synchrotron diffraction and Mossbauer spectroscopy on Ba-2(Fe,W)(2)O-6 confirmed an Fe excess in this double-perovskite, better described as Ba2Fe(FexW1-x)O6-delta with x = 0.2. The crystal structure is cubic (Fm (3) over barm) down to 10 K, and a recently reported tetragonal structure of Ba2FeWO6 is critically reviewed. Magnetic properties of Ba-2(Fe,W1-xMox)(2)O-6 compounds were studied by SQUID measurements and revealed weak ferromagnetism at low temperatures, and T-C increases with more substitution of Mo for W.
