Microwave studies on FeSe superconductors

University of British Columbia

In this thesis, the microwave electrodynamic properties of stoichiometric FeSe are measured by a cavity perturbation technique based on a 940 MHz loop-gap resonator. Measurements surprisingly show, for the first time, that c-axis conductivity in stoichiometric FeSe superconductors exhibits a broad peak in its temperature-dependence, a phenomenon which was only observed for in-plane electrodynamics in the cuprates. This result implies that the charge transfer between FeSe-planes is enhanced by the development of long transport quasiparticle lifetimes below Tc.
