Decoupling of Lattice and Orbital Degrees of Freedom in an Iron-Pnictide Superconductor
Christian E. Matt, O. Ivashko, M. Horio +16
The interplay of structural and electronic phases in iron-based superconductors is a central theme in the search for the superconducting pairing mechanism. While electronic nematic…
ARPES observation of Mn-pnictide hybridization and negligible band structure renormalization in BaMnAs and BaMnSb
W. -L. Zhang, P. Richard, A. van Roekeghem +14
We performed an angle-resolved photoemission spectroscopy study of BaMnAs and BaMnSb, which are isostructural to the parent compound BaFeAs of the 122 famil…
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…
Observation of high-Tc superconductivity in rectangular FeSe/STO(110) monolayer
P. Zhang, X. -L. Peng, T. Qian +12
It is well known that superconductivity in Fe-based materials is favoured under tetragonal symmetry, whereas competing orders such as spin-density-wave (SDW) and nematic orders eme…
Observation of two distinct band splittings in FeSe
P. Zhang, T. Qian, P. Richard +10
We report the temperature evolution of the detailed electronic band structure in FeSe single-crystals measured by angle-resolved photoemission spectroscopy (ARPES), including the d…
