Abstract

The infinite-layer (IL) systems have rather simple crystal structures and thereby offer an ideal system for an improved understanding of the phenomenon of high-T_c superconductivity. The production of IL compounds is by no means trivial, since the synthesis of single-phase material requires both high pressures and high temperatures. The infinite-layer compounds of the (Sr, Ln)CuO₂ family have been prepared by a new synthesis method from the low-pressure phase of SrCuO₂ and NdCuO₂ as starting materials. The actual rare-earth content in the IL phase is shown to depend on both temperature and pressure. Crystal structure of the IL samples have been studied using neutron powder diffraction and X-ray measurements.
