Abstract anzeigen
Thick films containing ultrafine multilayer structures of two complex metal oxides are grown with a single, sectored target in conjunction with pulsed laser deposition on stationary or moving templates. This process is demonstrated with the high‐temperature superconductors YBa2Cu3Oy and EuBa2Cu3Oy. Multilayer periodicities (see figure) as low as 5.5 nm (approximately five unit cells) are obtained in thick films (1.84 μm ≈ 335 bilayer pairs) with improved superconducting properties.

Abstract anzeigen
This report describes recent developments of second-generation Y1Ba2Cu3O7−δ (YBCO) coated conductors deposited on biaxially textured MgO templates. The materials system architecture implemented to achieve high critical currents in YBCO films is described. The average full-width at half maximum (FWHM) in-plane texture obtained for MgO films processed on meter-length tapes is 7°, while that for the YBCO films is 3°. The best YBCO in-plane values approach 2° and the out-of-plane values approach 1°. Critical currents (1 cm wide tapes, 75 K, self field) have attained 423 A for 7 cm length and 233 A for 50 cm length tapes.
