Abstract

The crystal structures of the C polymorphs of the solid solutions Li0.5-3xRE0.5+xTiO3, RE=Pr,Nd, x∼0.05, have been refined by the Rietveld method from powder neutron diffraction data. At room temperature the C phases are orthorhombic and adopt the GdFeO3 structure type. The Li+ and RE cations share the A site, but with the Li+ displaced away from the ideal position.
