摘要： When a cuprate oxide LnBa.sub.2 Cu.sub.3 O.sub.7-x (Ln=Y, Pr or Sm; 0.30.ltoreq.x.ltoreq.1) single crystal is heated for growing a film epitaxially on the crystal or for smoothing a damaged surface of the single crystal, many large protrusions occur on the surface of the oxide single crystal substrate or the film. The smooth surface of the oxides becomes rugged by the protrusions. According to the present invention, however, the oxide substrate or the oxide superconductor film can be heated in an atmosphere including oxygen of a partial pressure between 50 mTorr and 200 mTorr to prevent the protrusions from originating on the surface of the heated oxides.
