摘要

Two series of Y_1-xCa_xBa₂Cu₃O_y, x = 0.05 and 0.10, have been studied by O-1s X-ray absorption near-edge spectroscopy using synchrotron radiation. The characteristics of the decrease of T_c with the decrease of the oxygen content, y, are found different for the series of x = 0.05 and x = 0.10. The former reveals the importance of the holes on the apical oxygen sites. Through a cross examination between these two series of samples, direct evidences are observed that the reduction of the number of holes on the apical oxygen sites has a negative effect on the superconductivity in the underdoped region of Ca-doped YBCO system.
