抄録

The results of a study into the annealing behaviour of an oxygen-rich superconductor, YLa_1.6Ba_3.4Cu₆O _14+or-y(-0.12<y<0.47), are reported. As with YBa ₂Cu₃O_7-d, the oxygen level increases with decreasing quench temperature (T_q), 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_q, and the superconducting materials in this series are tetragonal.
