  摘要：

  多晶 NH4FeF4 系统在 110-300 K 温度范围内的 1H NMR 研究揭示了线宽和自旋晶格弛豫率的异常增加，T1-1 接近反铁磁转变温度 135 K。在临界区域, T1-1 发散为 epsilon -0.50，其中 epsilon = (T-TN) / TN。指数表明在转变点附近有明显的 3D 磁相互作用。然而，宽临界区 (135 K

  A technique has been developed for fluorinating the pyrochlore oxide Bi1.8Fe0.2FeSbO7, and a compound with the composition Bi1.8Fe1.2SbO7-x/2Fx has been obtained. The synthesized oxyfluoride also has the pyrochlore structure (sp. gr. Fd (3) over barm), with a lattice parameter a = 10.4443(1) (A) over circle (R-wp = 5.2). It has been shown that the charge balance upon fluorine substitution for oxygen is maintained not through partial reduction of Fe3+ to Fe2+ but through the incorporation of fluorine into oxygen vacancies. The magnetic behavior of the fluorinated pyrochlore phase is determined by the persisting frustration of the octahedral sublattice, which is responsible for the development of a spin glass state below T-f = 12 K. The fluorination-induced changes in the anion sublattice led to an increase in the antiferromagnetic exchange interaction between neighboring Fe3+ ions and changes in the dynamic properties of the spin glass phase.
