Abstract

We report a new superconductor, (Ca,A)₂CuO_2+yBr_2-y,:A=(Na,K) (T_c=24 K) with apical bromines synthesized under high pressure . X-ray powder diffraction shows that the superconducting phase has a tetragonal structure with a=3.858 Å, c=17.257 Å. This structure is so called La₂CuO₄ (214) type with an apical site of octahedral CuO₆ being almost occupied by the bromine atoms.
