Evidence of a universal relation between electron-mode coupling and Tc in Ba1-xKxFe2As2 superconductor from Laser ARPES
W. Malaeb, T. Shimojima, Y. Ishida +15
We performed a Laser angle-resolved photoemission spectroscopy (ARPES) study on a wide doping range of Ba1-xKxFe2As2 (BaK) iron-based superconductor. We observed a robust low-bindi…
Superconducting gap with sign reversal between hole pockets in heavily hole-doped Ba1-xKxFe2As2
D. Watanabe, T. Yamashita, Y. Kawamoto +16
To gain insight into the unconventional superconductivity of Fe-pnictides with no electron pockets, we measure the thermal conductivity and penetration depth in the heavily…
Evidence for exclusion of the possibility of -wave superconducting-gap symmetry in Ba-doped KFeAs
Y. Ota, K. Okazaki, Y. Kotani +12
We have investigated the superconducting(SC)-gap anisotropy for several Ba-doped KFeAs samples using laser-based angle-resolved photoemission spectroscopy. We show that the…
Importance of both spin and orbital fluctuations in BaFe2(As1-xPx)2 : Evidence from superconducting gap anisotropy
T. Yoshida, S. Ideta, T. Shimojima +32
In the iron pnictide superconductors, two distinct unconventional mechanisms of superconductivity have been put forth: One is mediated by spin fluctuations leading to the s+- state…
From d-wave to s-wave pairing in the iron-pnictide superconductor (Ba,K)Fe2As2
J. -Ph. Reid, A. Juneau-Fecteau, R. T. Gordon +18
The nature of the pairing state in iron-based superconductors is the subject of much debate. Here we argue that in one material, the stoichiometric iron pnictide KFe2As2, there is…
Anomalous two peak structure in the Angle-resolved Photoemission Spectra of Ba1-xKxFe2As2
T. Shimojima, W. Malaeb, K. Ohgushi +13
The electronic structure near the Fermi level (EF) of Ba1-xKxFe2As2 (BaK122 ; x = 0.2 - 0.7) is studied using laser ultrahigh-resolution angle-resolved photoemission spectroscopy(A…
Abrupt change in the energy gap of superconducting Ba1-xKxFe2As2 single crystals with hole doping
W. Malaeb, T. Shimojima, Y. Ishida +17
We performed a Laser angle-resolved photoemission spectroscopy (ARPES) study on a wide doping range of Ba1-xKxFe2As2 (BaK) and precisely determined the doping evolution of the supe…
Universal heat conduction in the iron-arsenide superconductor KFe2As2 : Evidence of a d-wave state
J. -Ph. Reid, M. A. Tanatar, A. Juneau-Fecteau +12
The thermal conductivity of the iron-arsenide superconductor KFe2As2 was measured down to 50 mK for a heat current parallel and perpendicular to the tetragonal c-axis. A residual l…
The pairing state in KFe2As2 studied by measurements of the magnetic vortex lattice
H. Kawano-Furukawa, C. J. Bowell, J. S. White +14
Understanding the mechanism and symmetry of electron pairing in iron-based superconductors represents an important challenge in condensed matter physics [1-3]. The observation of m…
Evidence for superconducting gap nodes in the zone-centered hole bands of KFe2As2 from magnetic penetration-depth measurements
K. Hashimoto, A. Serafin, S. Tonegawa +13
Among the iron-based pnictide superconductors the material KFeAs is unusual in that its Fermi surface does not consist of quasi-nested electron and hole pockets. Here we re…
