Identification and structural implications of the 90 K superconducting phase
The phase relations of Cu-containing compounds in the system Y/sub 2/O/sub 3/-BaO-CuO were determined at a temperature of about 950/sup 0/C and a fixed partial pressure of 0.21 atm of oxygen. Mixtures of Y/sub 2/O/sub 3/, BaCO/sub 3/, and CuO were heated and the products identified by powder X-ray d...
