Vf. Vratskikh et al., OFF-AXIS PULSED-LASER DEPOSITION OF CEO2 BUFFER AND YBA2CU3O7-DELTA THIN-FILM ON BOTH SIDES OF A SAPPHIRE SUBSTRATE IN A ONE-STEP PROCESS, Superconductor science and technology, 10(10), 1997, pp. 766-768
Microwave surface resistance values of 0.6 m Omega at a temperature 77
K and frequency 10 GHz were measured on YBa2Cu3O7-delta thin films pr
epared on both sides of a CeO2-buffered R-Al2O3 substrate by off-axis
pulsed laser deposition in a one-step process. The duration of the com
pletely in situ fabrication of the double-sided YBa2Cu3O7/CeO2 film wa
s determined io be 35 min. The use of the modified oven design heater
enabled an adequately stable and precise temperature control during th
e deposition ore a free-sanding substrate.
