Measurement of the penetration depth λ(T) as a function of temperature using millimeter wave transmission in the range 130-500GHz are reported for three YBa2 (YBCO) laser ablated thin films. Two films, deposited on a LaAlO3 substrate (Tc=90.2 K), ex

We have deduced the penetration depth λ(T) on YBa2Cu3O7 thin films from transmission measurement in the range 100–550 GHz. Our data yield simultaneously the absolute value and the temperature dependence of λ(T). In lower-quality films, we report

Using a subpicosecond electro-optic sampling technique, we have characterized the photoresponse of current-biased YBa/sub 2/Cu/sub 3/O/sub 7-x/ (YBCO) photodetectors, designed as 5-/spl mu/m-wide and 7-/spl mu/m-long microbridges patterned in 100-nm-

Point defects have been introduced into YBa/sub 2/Cu/sub 3/O/sub 7/ through low energy helium ion irradiation in order to probe the origin of dissipation in a current-carrying superconductor. Resistivity, infrared reflectance and x-ray diffraction me

The yttrium barium copper oxide (YBCO) high- T c superconductor has a sharp dissipation peak at the magnetic flux phase transformation temperature, whether in the form of a single crystal, ceramic, or thin film. This peak has been proposed as the bas

Photoresponse signals with widths as short as 1.5 ps are observed from epitaxial YBa2Cu3O7−δ thin films using electro‐optic sampling techniques. Voltage transients less than 2 ps wide are seen in 100‐ and 200‐nm films exposed to 150‐fs las
