Abstract

We report the XRD observation of the YBa₂Cu₃O₇/YBa₂Cu₃O ₈ structural isothermal transformation at room temperature and atmospheric oxygen pressure. It is shown that this structural transformation runs according to the scheme: YBa₂Cu₃O_7-x→ → Y₂Ba₄Cu₇O_14+y,→YBa ₂Cu₄O₈ . These results are the first straightforward experimental evidence that the superconducting orthorhombic YBa₂Cu₃O_7-x (x ≈ 0) is metastable under the ambient pressure at moderate temperature.
