  • Hydration, Structure, and Superconductivity of KOs2O6·nH2O
  • 2008
  • In: Chemistry of Materials. - : American Chemical Society (ACS). - 0897-4756 .- 1520-5002. ; 20:4, s. 1652-1659
  • Journal article (peer-reviewed)abstract
    • In moist air or by contact with water during washing, KOs2O6 absorbs water molecules into the structure to produce KOs2O6·nH2O, 0 < n < 0.1. This water is reversibly lost on heating above ∼430 K in flowing or static gas environments. Variable temperature powder neutron and X-ray diffraction show that an increase in lattice parameter occurs when water enters the pyrochlore structure and the water molecules are located in the α cages displacing a portion of the potassium ions to adjacent sites. On removing water the lattice parameter and structure revert to those of the normal β-pyrochlore crystallographic description. Hydration has the effect of reducing the onset of superconducting behavior from a critical temperature of 10.25 K in fully dry KOs2O6 to 9.75 K in KOs2O6·0.1H2O.

  • The structure of superconducting RbOs2O6 between 2 K and 300 K
  • 2007
  • In: Journal of Materials Chemistry. - : Royal Society of Chemistry (RSC). ; 17:2, s. 160-163
  • Journal article (peer-reviewed)abstract
    • The structure of RbOs2O6 can be described fully in the Fd (3) over barm space group between 2 and 298 K and large thermal displacement factors associated with the Rb ion are probably typical of this structure type and the site occupied.
