Superconducting Y/sub 1/Ba/sub 2/Cu/sub 3/O/sub 7-//sub 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 SrTiO/sub 3/(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 T/sub c/(R = 0) at 82 K was obtained. A lower limit of the average J/sub c/ in the plane is 10/sup 3/ A/cm/sup 2/ at 77 K 5 x 10/sup 4/ A/cm/sup 2/ at 70 K, and 10/sup 6/ A/cm/sup 2/ at 4.2 K.
