Abstract

Superconducting Y1Ba2Cu3O7-x films were produced by metal molecular-beam epitaxy with one electron beam and two thermal cells and a molecular oxygen-gas source. The films were epitaxially grown on SrTiO3(100) with an a-axis orientation perpendicular to the plane, and b and c axes ordered in the plane. A sharp resistive superconducting transition with Tc(R=0) at 82 K was obtained. A lower limit of the average Jc in the plane is 103 A/cm2 at 77 K, 5×104 A/cm2 at 70 K, and 106 A/cm2 at 4.2 K.
