J. Wosik et al., METHOD FOR OBSERVING THE SUPERCONDUCTING PROXIMITY EFFECT FROM MICROWAVE-ABSORPTION MEASUREMENTS, Physica. C, Superconductivity, 235, 1994, pp. 2009-2010
We report a microwave and cross-sectional TEM/SAED study of the effect
of deposition conditions on the interface properties of Ag/(001) and
(103) oriented YBCO bilayer films. The bilayers were deposited in-situ
with a two step large area laser ablation process on (001) LaAlO3 and
(110) SrTiO3. Surprisingly large differences in R(s) values of layere
d films with the same nominal thickness but with different process par
ameters are explained and the possibility of proximity effect for both
c-axis and (110) oriented films is discussed.
