Beschreibungen/Notizen

• Coherent time-domain spectroscopy was used to measure the complex transmission tensor of several YBa[sub 2]Cu[sub 3]O[sub 7[minus][delta]] thin films in magnetic fields up to 6 T temperatures from 10 to 200 K. The complex conductivity tensor was determined from transmission measurements in the frequency range 150--800 GHz without the need for Kramers-Kronig analysis. Both the real and imaginary parts of [sigma][sub [ital x][ital y]] were found to peak near 40 K, exceeding their normal state values by more than a factor of 10. This behavior is ascribed to the Hall effect of quasiparticles in the superconducting state.
