Superconducting Films of YBa2Cu3Ox and Bi-Sr-Ca-Cu-O Fabricated by Electron-Beam Deposition with a Single Source

Abstract
Superconducting thin films of YBa2Cu3O x and Bi-Sr-Ca-Cu-O were made by electron-beam deposition with a sintered pellet as an evaporation source. With a c-axis orientation perpendicular to the substrates, YBa2Cu3O x grows on MgO(100) and Bi-Sr-Ca-Cu-O grows on SrTiO3(100), and the critical temperatures for zero resistivity were 78 and 72 K, respectively.
