✦ Synopsis

The structure analysis and superconductivity in the mixed ccmpounds L~~,~~S~O.ISCU;-.MIOI-~ ( O<x<O.O3 )( M=Mg,Mn ) were studied. It is observed that the crystal structure is not distorted. The Superconducting transition temperature Tc drops linearly with the increase of the M(M=Mg,Mn) content. Superconductivity is suppressed above x=0.022 for Mg doping and x=0.012 for Mn doping, respectively. The difference of doping results for magnetic and nonmagnetic ions is given, and the origin of the depression on Tc is discussed in this paper.
