Abstract

We have successfully synthesized new superconductor EuSr₂Cu ₂Nb_1-xSn_xO_8-y of the so-called Nb-1212 system, where Nb is substituted for Cu1 in the RE-123 (RE= rare earth elements) type structure by the hole-doping through the partial substitution of Sn⁴⁺ for Nb⁵⁺. The highest value of the superconductivity of the superconducting transition temperature, T_c, is about 40 K at x = 0.2. This is the first superconductor in the Nb-1212 system.
