Abstract

Three new oxycarbonate superconductors recently obtained in our laboratory are described. (1) Sr₂CuO₂(CO₃)_1-x(BO₃)_x (T_c = 35 K) was synthesized under ambient pressure, providing a new method for carrier doping on the layered copper oxycarbonate system. (2) Ca_n(Ca, Sr)₂Cu_n+1(CO₃)O_y (n = 1, 2, 3) was synthesized under high pressure. Superconductivity was achieved by substituting (BO₃)^3- for a part of (CO₃)^2-. (3) A new Hg system HgBa₂Sr₂Cu₂(CO₃)O_6+δwas synthesized. T_c obtained from the magnetic susceptibility is about 66 K.
