Microwave impedance study of superconducting (Li1-xFex)OHFeSe single crystal

Microwave (MW) surface impedance Zs =Rs +iXs of the recently discovered high-Tc iron-based superconductor (Li0.84Fe0.16)OHFe0.98Se single crystal was measured for the first time. The special X-band "hot finger" resonator allowed carrying out measurements when temperature of the sample under test can be varied from 2K to 90K and in the same time temperature of the resonator remained constant (4.2K). The unusual and important inequality Rs
