Description

K2NiF4-type Sr2CuO2+δCl2-y superconductor was synthesized with partial substitution of oxygen for apical chlorine using a high-pressure technique. This phase has been studied by transmission electron diffraction, convergent beam electron diffraction, x-ray powder diffraction, energy dispersive analysis of x-ray, electron energy loss spectroscopy and high-resolution electron microscopy. The crystal structure with a space group of I4/mmm has been determined, and the lattice parameters are obtained as a b = 0.394?nm and c = 1.564?nm. Edge dislocations with Burgers vector b=1/2c are observed in the phase
