Abstract
Superconducting 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 SrTi(100) with an -axis orientation perpendicular to the plane, and and axes ordered in the plane. A sharp resistive superconducting transition with at 82 K was obtained. A lower limit of the average in the plane is A/ at 77 K, 5× A/ at 70 K, and A/ at 4.2 K.
