Abstract
Three new oxycarbonate superconductors recently obtained in our laboratory are described. (1) Sr2CuO2(CO3)1-x(BO3)x (Tc = 35 K) was synthesized under ambient pressure, providing a new method for carrier doping on the layered copper oxycarbonate system. (2) Can(Ca, Sr)2Cun+1(CO3)Oy (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)O6+δwas synthesized. Tc obtained from the magnetic susceptibility is about 66 K.
