Oxygen Stability in YBa sub 2 Cu sub 3 O sub 7--x

The high T sub c superconductor YBa sub 2 Cu sub 3 O sub 7--x has been found to lose appreciable amount of oxygen in a surprisingly low temperature range ( approx 425-630K), which drastically degrades the superconducting property. Accompanying this oxygen loss, the resistance behaviour has also been...

Description
Summary:The high T sub c superconductor YBa sub 2 Cu sub 3 O sub 7--x has been found to lose appreciable amount of oxygen in a surprisingly low temperature range ( approx 425-630K), which drastically degrades the superconducting property. Accompanying this oxygen loss, the resistance behaviour has also been found to change from metallic to semiconducting. 12 ref.--AA
