Powder Diffraction Data for the Imperfect Pyrochlore Terbium Titanate, Tb2Ti2O7
Published online by Cambridge University Press: 10 January 2013
Abstract
Notwithstanding expectations of a pure pyrochlore structure (cubic space group Fd3m (227) with Z=8) terbium titanate turns out, like many pyrochlore compounds, to be slightly disordered in the cation and the oxygen lattice so that it partially (for 10%) resembles a structure with fluorite properties (space group Fm3m (225) with Z = 2).
