Abstract
The stabilization of the quadruple perovskite structure Ln2Ba2Cu2Ti2O11 as a function of the constituent lanthanides has been investigated. Powder X-ray data show that the mixed A-site compositions Ln′Ln″Ba2Cu2Ti2O11 (Ln′Ln″ = LaY, LaHo, LaEr, and NdDy) concertedly order to form distinct CuO2 2- and TiO2 double layers. In addition the A cations (Ln′, Ln″, and Ba) order on three distinct sites, with the smaller lanthanide (Ln″) occupying the 8-coordinate site between contracted copper-oxygen planes.
