摘要：
We investigated the oxygen isotope effect in superconducting Co substituted YBCO. Co concentrations between 4 and 13% were used. The transition temperature T(c) falls monotonously to 22.7 K for x = 0.13. The oxygen isotope exponent alpha0 rises from alpha0 = 0.08 (4% Co) to alpha0 = 0.46 (x = 0.13%) at the lowest transition temperature. The dependence of alpha0 on T(c) is intermediate between that for Zn and Pr substituted YBCO.
