| Popis: | Intrinsic properties, such as the London penetration depth /spl lambda//sub L/, and the surface resistance R/sub s/, can be estimated in high-T/sub c/ films by studying self-induced electromagnetic resonances (Fiske modes) in bicrystal grain boundaries. Grain boundaries, 4-30 /spl mu/m long and 0.2 /spl mu/m thick in YBa/sub 2/Cu/sub 3/O/sub 7/ made on yttria-stabilized zirconia 0-32/spl deg/ [001]-tilt bicrystals were investigated. Typical values obtained for /spl lambda//sub L/ and R/sub s/ (at approximately 200-400 GHz) are 110-170 nm, and 20-710 m /spl Omega/, respectively. > |
