Ca 2 CuO 2 Cl 2Γy Br y (0 6 y 6 2) has the K 2 NiF 4 -type structure with halogens (Cl and Br) at their apical sites and superconductivity can be achieved by substituting Ca 2+ sites with Na + . We have succeeded in making a comprehensive superconducting phase diagram of Ca 2Γx Na x CuO 2 Cl 2Γy Br
Multilayer of Nb/NbZr shows an upturn behavior in the parallel upper critical field HaN(T ). In this work, we studied the critical current density J~ as a function of magnetic field H and of the angle between H and film plane at various temperatures. From the non-monotonic behavior Jc(H), we found t
