    Tc, onset, fluctuation and intergrain connection in the Bi2−xGexSr2CaCu2O8+δ

    Resistive transitions in Bi2−xGexSr2CaCu2O8+δ(x=0-0.3) prepared by the solid state reaction method were investigated. The Tc,onset’s of the as sintered pellets were approximately 74 K and 80 K for x=0 and x>0 res...
