Effect of K Doping on Phonons in Ba1-xKxFe2As2
Chul-Ho Lee, Kunihiro Kihou, Kazumasa Horigane +8
The lattice dynamics of Ba1-xKxFe2As2 (x = 0.00, 0.27) have been studied by inelastic X-ray scattering measurement at room temperature. K doping induces the softening and broadenin…
Possible Multiple Gap Superconductivity with Line Nodes in Heavily Hole-Doped Superconductor KFe2As2 Studied by 75As-NQR and Specific Heat
H. Fukazawa, Y. Yamada, K. Kondo +12
We report the 75As nuclear quadrupole resonance (NQR) and specific heat measurements of the heavily hole-doped superconductor KFe2As2 (Tc = 3.5 K). The spin-lattice relaxation rate…
Three-dimensional electronic structure of superconducting iron pnictides observed by angle-resolved photoemission spectroscopy
Walid Malaeb, Teppei Yoshida, Atsushi Fujimori +10
We have performed an angle-resolved photoemission spectroscopy (ARPES) study of the undoped and electron-doped iron pnictides BaFe2\_{-x}CoxAs2 (Ba122) (x=0, 0.14) and studied the…
Strong-coupling Spin-singlet Superconductivity with Multiple Full Gaps in Hole-doped BaKFeAs Probed by Fe-NMR
M. Yashima, H. Nishimura, H. Mukuda +7
We present Fe-NMR measurements of the novel normal and superconducting-state characteristics of the iron-arsenide superconductor BaKFeAs ( = 38…
Inverse Iron Isotope Effect on the transition temperature of the (Ba,K)Fe2As2 superconductor
Parasharam M. Shirage, Kunihiro Kihou, Kiichi Miyazawa +6
We report that (Ba,K)Fe2As2 superconductor (a transition temperature, Tc = 38 K) shows inverse Iron isotope effect (-0.18) (the sample including the larger atomic weight of Fe depi…
75As NMR Study of Hole-Doped Superconductor Ba1-xKxFe2As2 (Tc = 38K)
H. Fukazawa, T. Yamazaki, K. Kondo +8
We report the 75As nuclear magnetic resonance (NMR) measurement of the hole-doped superconductor Ba1-xKxFe2As2 with different lattice parameters and different superconducting volum…
