Abstract
A copper oxy-chloride superconductor La1.6Sr0.4CaCu2O4+deltaCl2-y is p repared at ambient pressure using the traditional solid state reaction method. The structure of the superconductor belongs to the structure type of 212 cuprate superconductors with the lattice parameters a = 3. 827 Angstrom, c = 19.42 Angstrom and space group I4/mmm. The supercond ucting transition temperature (T-0) of this material is 34 K, and the carrier concentration in it is controlled not only by cation substitut ion, but also by anion substitution.
