Abstract
A recently proposed lattice-parameter (a 0(ss)) model for parent fluorite-type MO2-LnO1.5 solid solutions (M4 + = Ce and Th; Ln3 + = lanthanide) has been extended to more complex LnO1.5-stabilized zirconia (hafnia) (M4 + = Zr(Hf)) with pyrochlore-type ordering and its-associated broad a 0(ss) hump, using key Ln (Eu and Gd)-Mössbauer and related local-structure data.
