Abstract
Superconductive films of YbBa2Cu3O7 have been epitaxially grown on SrTiO3 substrate by a novel liquid‐gas‐solidification process. A layer of metallic YbBa2Cu3 melt was coated on the substrate and in situ oxidized. The oxide films grown on the SrTiO3 (100) substrate are epitaxially oriented in structure with the c axis normal to the plane film. Values of Tc (R=0) of 82 K with a transition width of 1 K have been achieved. The critical current density Jc is typically 105 A/cm2 at 50 K and 104 A/cm2 at 77 K.Keywords
