Abstract

Time-domain spectroscopy is a powerful probe of the electrical response of high-Tc thin films in the millimeter and submillimeter regime. The ability to measure both the real and imaginary parts of the response without Kramers-Kronig analysis is particularly useful in understanding the dynamics of the superconducting state. We have recently designed a time- domain spectrometer which operates in conjunction with a superconducting magnet-cryostat in order to measure the change in the resistivity with field. Using this system we have measured the resistivity tensor of YBCO as a function of frequency from 100 to 800 GHz in a field of 0 to 6 Tesla. We interpret these results in terms of the combined vortex and quasiparticle response in the mixed state, and we believe we have made the first observation of the Hall response of quasiparticles at temperatures well below T.
