Abstract

The compensated systems of Y_1-xSr_xBa _2-xLa_xCu₃O_y were synthesized and characterized by DC magnetization measurements and X-ray diffraction. The structures of the samples were refined by Rietveld method. Although the carrier concentration in the samples is constant at different doping levels, the superconductivity evidently changes. The combinative energy in the system was calculated and it was discovered that the decrease of T_c has close relationship with the increase of the combinative energy. It is suggested that the structural factor should be taken into account when considering the mechanism of high T_c superconductivity.
