Abstract :
Electron-microscopic investigations about growing YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// films on monocrystalline Ni substrates with buffer layers of MgO have been carried out. The condition, under which the forming epitaxial YBCO films with T/sub c/(R=0)=85 K, and j/sub c/(H=0.77 K)/spl ap/ 2/spl times/10/sup 5/A/cm/sup 2/ are proceeding, has been determined.<>
