Abstract

A new family of superconductors containing carbonate group has been reviewed. Especially, we emphasize the three new oxycarbonate compounds recently found in our laboratory. 1. Sr₂CuO₂(CO₃)_1-x(BO₃)_x (T_c≈35K) have been synthesized under an ambient pressure. This idea suggests the new method for carrier doping on layered copper oxycarbonate system. 2. Can(Ca,Sr)₂Cu_n+1(CO₃)O_y (n=1, 2, 3) have been synthesized under a high pressure(T_c 108K). The superconductivity could be achieved by substituting (BO₃)^3- for a part of (CO₃)^2-. 3. A new Hg-system HgBa₂Sr₂Cu₂(CO₃)O_6+δ has been synthesized. T_c obtained from the magnetic susceptibility is about 66K.
