Abstract
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 crystal structure, microstructure and superconductivity of these samples have been studied with use of neutron powder diffraction, optical micrographs, energy-dispersive X-ray analysis, magnetic-susceptibility and electrical-resistivity measurements. The ratio of the lattice constants a/c as an empirical parameter for the existence of superconductivity in the electron-doped infinite-layer compounds is discussed.
