Nonmetallic Low-Temperature Normal State of K0.70Fe1.46Se1.85Te0.15
Kefeng Wang, Hyejin Ryu, Erik Kampert +4
The normal-state in-plane resistivity below the zero-field superconducting transition temperature and the upper critical field Hc2 were measured by suppressing superconductiv…

Physical properties of KxNi2-ySe2 single crystals
Hechang Lei, Kefeng Wang, Hyejin Ryu +3
We have synthesized K0.95(1)Ni1.86(2)Se2 single crystals. The single crystals contain K and Ni deficiencies not observed in KNi2Se2 polycrystals. Unlike KNi2Se2 polycrystals, the s…

Multiband effects on beta-FeSe single crystals
Hechang Lei, D. Graf, Rongwei Hu +4
We present the upper critical fields Hc2(T) and Hall effect in beta-FeSe single crystals. The Hc2(T) increases as the temperature is lowered for field applied parallel and perpendi…
