Abstract

We have successfully synthesized a new 0201-type superconductor Sr₂CuO_2+δCl_2-y under high pressure using the "apical oxygen doping" mechanism, i.e., partially substituting the oxygen for chlorine at the "apical" site. The X-ray diffraction refinements as well as electron microcopy observations suggest that the new superconductor crystallizes into a K₂NiF₄ structure with tetragonal unit cell of a = 3.92 Å, c = 15.65 Å. Magnetic susceptibility as well as resistance measurement demonstrates the presence of a bulk superconductivity with transition temperature (T_c) at 30 K in Sr₂CuO_2+δCl_2-y superconductor.
