Single Crystal Growth and Characterization of the Iron-Based Superconductor KFe2As2 Synthesized by KAs Flux Method
Kunihiro Kihou, Taku Saito, Shigeyuki Ishida +9
Centimeter sized platelet single crystals of KFe2As2 were grown using a self-flux method. An encapsulation technique using commercial stainless steel container allowed the stable c…
Strong carrier-scattering in iron-pnictide superconductors with highest Tc obtained from charge transport experiments
S. Ishida, M. Nakajima, Y. Tomioka +10
Characteristic normal-state charge transport is found in the oxygen-deficient iron-arsenides LnFeAsO1-y (Ln: La and Nd) with the highest Tc's among known Fe-based superconductors.…
Evolution of the optical spectrum with doping in iron pnictides Ba(Fe1-xCox)2As2
M. Nakajima, S. Ishida, K. Kihou +9
We investigated the optical spectrum of Ba(Fe1-xCox)2As2 single crystals with various doping levels. It is found that the low-energy optical conductivity spectrum of this system ca…
