Rapid solidification of oxide superconductors in the Y-Ba-Cu-O system
- 1. Massachusetts Institute of Technology, Cambridge (USA)
Description
Three compositions which lie along the YBa2Cu3O9-x-BaCuO2 tie-line were melted and solidified with different cooling rates. Rapid solidification of all three compositions results in new, previously unreported phases. Slower solidification rates yield multi-phase materials. Annealing all three compositions in O2 transforms them to the YBa2Cu3O9-x orthorhombic phase plus varying amounts of BaCuO2. The annealed materials all show superconductivity with an average Tc = 88.5 K as measured through the resistivity, which is in good agreement with measurements on a SQUID magnetometer
