High T c superconductor M-La-Cu-O systems (M=Ba, Sr), with the composition (M x La 1- x ) 2 CuO 4- y , have been prepared by a ceramic technique and the compositional change of T c -value have been examined. Then in each of systems the partial substitution of Ag or Hg for Cu brought the increase of T c -value.
