Electronic properties across metal-insulator transition in \beta-pyrochlore-type CsW2O6 epitaxial films [PDF]
In CsW2O6, which undergoes a metal-insulator transition (MIT) at 213 K, the emergence of exotic properties associated with rattling motion of Cs is expected owing to its characteristic \beta-pyrochlore-type structure. However, a hurdle for crystal growth

XPS and NEXAFS Studies of Zn-Doped Bismuth Iron Tantalate Pyrochlore
The effect of Zn-doping on the phase composition and optical properties of the Bi2ZnxFe1-xTa2O9.5-Δ (x = 0.3, 0.5, 0.7) was studied. XRD data showed that the samples crystallize in the structural type of pyrochlore (sp. gr.Fd-3m). For all the samples, an
