Description
In the system Bi-0212 the carrier concentration can be changed by both cation substitution and oxygen content. The crystal structure of Ca substituted material was refined from neutron powder diffraction data for Bi0.5Sr1.5Ca0.5Y0.5Cu1.5Fe0.5Oy. It is shown that extra oxygen is introduced in the cation layers between the double sheets of Cu/O pyramids. In superconducting material the familiar dependence of Tc on the hole carrier concentration is observed. The higher Tc is situated at 75 K. (orig.)
