以Y、Ba和Cu的β-二酮化合物为原料，采用化学气相沉积法制备了YBa 2 Cu 3 O 7 −x高温超导薄膜。薄膜在SrTiO 3（100）衬底上外延生长。观察到垂直于基板平面的c轴取向。在84 K下获得了锐阻性超导转变，其Tc（R=0）。77 K时的最大临界电流密度为2×104 A/cm 2。
High Tc superconducting YBa2 Cu3 O7−x films were prepared by chemical vapor deposition using β‐diketonates of Y, Ba, and Cu as source materials. The films were epitaxially grown on SrTiO3 (100) substrates. The c‐axis orientation perpendicular to the plane of the substrates was observed. A sharp resistive superconducting transition with Tc (R=0) at 84 K was obtained. The maximum critical‐current density at 77 K was 2×104 A/cm2 .
