摘要：

A new method of growing YBa2Ca3O7-x single crystals is described which uses an yttria crucible containing an appropriate BaOCuO mixture. The yttria crucible supplies yttrium to the melted mixture and YBa2Cu3O7-x crystallizes as the primary phase. Large single crystals are obtained which are superconducting at 40 K and the oxygen is probably homogeneously distributed. Almost complete reoxidation is achieved after 60 h of annealing at 450°C under oxygen, giving the superconducting phase at 88 K. © 1990.
