Observation of non-Fermi liquid behavior in hole-doped LiFeVAs
L. Y. Xing, X. Shi, P. Richard +12
We synthesized a series of V-doped LiFeVAs single crystals. The superconducting transition temperature of LiFeAs decreases rapidly at a rate of 7 K per 1\% V. The…
Hall effect in the extremely large magnetoresistance semimetal WTe
Yongkang Luo, H. Li, Y. M. Dai +7
We systematically measured the Hall effect in the extremely large magnetoresistance semimetal WTe. By carefully fitting the Hall resistivity to a two-band model, the temperatur…
Spin-Fluctuation-Induced Non-Fermi-Liquid Behavior with suppressed superconductivity in LiFeCoAs
Y. M. Dai, H. Miao, L. Y. Xing +12
A series of LiFeCoAs compounds with different Co concentrations have been studied by transport, optical spectroscopy, angle-resolved photoemission spectroscopy and nu…
Experimental discovery of Weyl semimetal TaAs
B. Q. Lv, H. M. Weng, B. B. Fu +11
Weyl semimetals are a class of materials that can be regarded as three-dimensional analogs of graphene breaking time reversal or inversion symmetry. Electrons in a Weyl semimetal b…
The anomaly Cu doping effects on LiFeAs superconductors
L. Y. Xing, H. Miao, X. C. Wang +5
The Cu substitution effect on the superconductivity of LiFeAs has been studied in comparison with Co/Ni substitution. It is found that the shrinking rate of the lattice parameter c…
Correlation-induced self-doping in intercalated iron-pnictide superconductor Ba2Ti2Fe2As4O
Junzhang Ma, Ambroise van Roekeghem, Pierre Richard +14
The electronic structure of the intercalated iron-based superconductor Ba2Ti2Fe2As4O (Tc - 21.5 K) has been investigated by using angle-resolved photoemission spectroscopy and comb…
Evolution from incoherent to coherent electronic states and its implications to superconductivity in FeTe1-xSex
E. Ieki, K. Nakayama, Y. Miyata +14
We have performed systematic angle-resolved photoemission spectroscopy (ARPES) of iron-chalcogenide superconductor FeTe1-xSex to elucidate the electronic states relevant to the sup…
Observation of well-defined quasi-particle over a wide energy range in quasi-2D system
L. -L. Jia, Z. -H. Liu, Y. -P. Cai +12
We report the observation by angle-resolved photoemission spectroscopy measurements of a highly anisotropic Dirac-cone structure in high quality SrMnBi2 crystals. We reveal a well-…
Coexistence of orbital degeneracy lifting and superconductivity in iron-based superconductors
H. Miao, L. -M. Wang, P. Richard +10
In contrast to conventional superconducting (SC) materials, superconductivity in high-temperature superconductors (HTCs) usually emerges in the presence of other fluctuating orders…
Orbital Characters Determined from Fermi Surface Intensity Patterns using Angle-Resolved Photoemission Spectroscopy
X. -P. Wang, P. Richard, Y. -B. Huang +10
In order to determine the orbital characters on the various Fermi surface pockets of the Fe-based superconductors BaKFeAs and FeSeTe,…
Unconventional Anisotropic s-Wave Superconducting Gaps of LiFeAs Iron-Pnictide Superconductor
K. Umezawa, Y. Li, H. Miao +10
We have performed high-resolution angle-resolved photoemission spectroscopy on Fe-based superconductor LiFeAs (Tc = 18 K). We reveal multiple nodeless superconducting (SC) gaps wit…
