Multiband behavior and non-metallic low-temperature state of K $_{0.50}$ Na $_{0.24}$ Fe $_{1.52}$ Se $_{2}$

Hyejin Ryu, F. Wolff-Fabris, J. B. Warren +3

We report evidence for multiband transport and an insulating low-temperature normal state in superconducting K $_{0.50}$ Na $_{0.24}$ Fe $_{1.52}$ Se $_{2}$ with $T_{c} \approx 20$ K. The…

Insulating and metallic spin glass in K $_{x}$ Fe $_{2 - δ - y}$ Ni $_{y}$ Se $_{2}$ (0.06 $\leq$ $y$ $\leq$ 1.44) single crystals

Hyejin Ryu, Milinda Abeykoon, Kefeng Wang +6

We report electron doping effects by Ni in K $_{x}$ Fe $_{2 - δ - y}$ Ni $_{y}$ Se $_{2}$ (0.06 $\leq$ $y$ $\leq$ 1.44) single crystal alloys. A rich ground state phase diagram is observed. S…
