Effect of the sample work function on alkali metal dosing induced electronic structure change
Saegyeol Jung, Yukiaki Ishida, Minsoo Kim +10
Alkali metal dosing (AMD) has been widely used as a way to control doping without chemical substitution. This technique, in combination with angle resolved photoemission spectrosco…
Evidence for a preformed Cooper pair model in the pseudogap spectra of a Ca10(Pt4As8)(Fe2As2)5 single crystal with a nodal superconducting gap
Yu-il Seo, Woo-jae Choi, Shin-ichi Kimura +1
For high-Tc superconductors, clarifying the role and origin of the pseudogap is essential for understanding the pairing mechanism. Among the various models describing the pseudogap…
Thermal activation energy of 3D vortex matter in NaFe1-xCoxAs (x=0.01, 0.03 and 0.07) single crystals
W. J. Choi, Y. I. Seo, D. Ahmad +1
We report on the thermally activated flux flow dependency on the doping dependent mixed state in NaFe1-xCoxAs (x=0.01, 0.03, and 0.07) crystals using the magnetoresistivity in the…
Optical properties of the optimally doped CaLa(PtAs)(FeAs) single crystal
Yu-il Seo, Woo-Jae Choi, Shin-ich Kimura +2
We have measured the reflectivity of the optimally doped CaLa(PtAs)(FeAs) single crystal ( = 32.8K) over the broad frequency range from 4…
Fluctuation magnetoconductivity in pristine and protonirradiated Ca8.5La1.5(Pt3As8)(Fe2As2)5 single crystals
D. Ahmad, Y. I. Seo, W. J. Choi +1
The influence of the proton irradiation on the thermally fluctuation-induced conductivity in Ca8.5La1.5(pt3As8)(Fe2As2)5 single crystal was investigatyed. The in-plane magnetocondu…
Superconducting properties and pseudogap from preformed Cooper pairs in the triclinic (CaFePtAs)PtAs
M. A. Surmach, F. Brückner, S. Kamusella +11
Using a combination of muon-spin relaxation (SR), inelastic neutron scattering (INS) and nuclear magnetic resonance (NMR), we investigated the novel iron-based superconductor wi…
