Phenomenological description of the microwave surface impedance and complex conductivity of high- single crystals
arXiv:cond-mat/9911211 · doi:10.1134/1.1326973
Abstract
Measurements of the microwave surface impedance and of the complex conductivity of high-quality, high- single crystals of YBCO, BSCCO, TBCCO, and TBCO are analyzed. Experimental data of and are compared with calculations based on a modified two-fluid model which includes temperature-dependent quasiparticle scattering and a unique temperature variation of the density of superconducting carriers. We elucidate agreement as well as disagreement of our analysis with the salient features of the experimental data. Existing microscopic models are reviewed which are based on unconventional symmetry types of the order parameter and on novel mechanisms of quasiparticle relaxation.
