| dc.description | The results of a study into the annealing behaviour of an oxygen-rich superconductor, YLa<sub>1.6</sub>Ba<sub>3.4</sub>Cu<sub>6</sub>O<sub>14+or-y</sub>(-0.12<y<0.47), are reported. As with YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7-d</sub>, the oxygen level increases with decreasing quench temperature (T<sub>q</sub>), and materials are superconducting only for anneals below 500 degrees C. However, an unusual behaviour of the unit cell symmetry has been observed by powder X-ray diffraction: orthorhombicity increases with increasing T<sub>q</sub>, and the superconducting materials in this series are tetragonal. |
