Abstract
The structural and superconducting properties of (Er1-xCax)Ba2-ySry(Cu 2.76Co0.24)O-z are investigated using X-ray diffraction, resistivity, ac susceptibility, and oxygen content measurements. Increasing the Sr content in (Er0.76Ca0.24)Ba2-ySry(Cu2.76Co0.24)O-z lowers the oxygen c ontent and decreases the T-c, which is attributed to the rearrangement of oxygen atoms in the basal plane. This suppression of T-c at y=0.6 cannot be improved by appropriate hole doping with Ca in (Er1-xCax)Ba1 .4Sr0.6(Cu2.76Co0.24)O-z for x=0.24-0.48.
