| 中文摘要 | the solid solutions of cdyfewo7, which are cubic pyrochlores of the type a(2)b(2)o(7), have been prepared and their structures were determined using ab initio method. rietveld refinement of the powder xrd data showed that cdyfewo7 adopted cubic (fd-3m) structure, while oxides crystallized in a defect-pyrochlore structure where both o (48f) and o'(8b) sites were partially occupied, and the frustrated cations sublattice precluded long range ordering of fe/w in the pyrochlore structure. charge distribution analysis also suggested incomplete occupation of different oxygen sites, thus the compound was non-stoichiometric, with the formula cdyfew0.982o6.94, magnetic measurements were carried out to find that fe ions were in the high spin trivalent state. curie weiss paramagnetism down to similar to 5 k and the characteristic superposition between fc and zfc suggested spin liquid rather than spin glass state. |
