Microwave Surface Impedance Measurements of the Electronic State and Dissipation of Magnetic Vortices in Superconducting Iron-Based LiFeAs Single Crystals
T. Okada, H. Takahashi, Y. Imai +4
LiFeAs is one of the iron-based superconductors having multiple gaps with the possible sign reversal. To clarify how those novel natures affect the energy dissipation of magnetic v…

Anomalous Temperature Dependence of the Superfluid Density Caused by Dirty-to-Clean Crossover in FeSeTe Single Crystals
Hideyuki Takahashi, Yoshinori Imai, Seiki Komiya +2
We report microwave surface impedances of FeSeTe single crystals measured at 12, 19, and 44 GHz. The penetration depth exhibits a power law behavior, $δλ_L=λ_L (T)-…
