摘要：
We have investigated the pressure dependence of superconducting transition temperature T-c in (Ru0.9M0.1)Sr2GdCu2O8 (M = V, Nb) oxide superconductor. The ferromagnetic transition temperature (T-f) and the magnitude of susceptibility below the Tf region are increases with V doping. On the other hand, these were clearly decreasing with Nd doping. The value of T-c in Nb-doped sample increased with increasing pressure. In contrast, the value of T-c for RuV1212 slightly decreased with increasing pressure. (C) 2003 Elsevier B.V.
