Abstract ： Chemical doping or substitutions were carried out in both the Ba site and Bi site in Ba-K-Bi-O superconductor. The large single crystals of Ba-K-M-Bi-O (M=Ca, Eu, In and T1) were prepared by using the electrocrystallization method. The resulting crystalline materials were characterized by x-ray photoelectron spectroscopy and magnetic method. The results show that partial substitutions of Ca or Eu in the Ba site suppress Tc more drastically than that of TI in the Bi site. All the present chemical substitutions result in a decrease in Tc .
