Angle-resolved spectroscopy study of Ni-based superconductor SrNiAs
L. -K. Zeng, P. Richard, A. van Roekeghem +7
We performed an angle-resolved photoemission spectroscopy study of the Ni-based superconductor SrNiAs. Electron and hole Fermi surface pockets are observed, but their diffe…
Resonant inelastic x-ray scattering study of electronic excitations in insulating KFeSe
H. Gretarsson, T. Nomura, I. Jarrige +9
We report an Fe -edge resonant inelastic X-ray scattering (RIXS) study of KFeSe. This material is an insulator, unlike many parent compounds of iron-based…
Single crystal growth and optical conductivity of SrPtAs superconductors
A. F. Fang, T. Dong, H. P. Wang +8
SrPtAs single crystals with CaBeGe-type structure were synthesized by self-melting technique. X-ray diffraction, transmission electron microscopy, electrical resist…
Hybridization gap versus hidden order gap in URuSi as revealed by optical spectroscopy
W. T. Guo, Z. G. Chen, T. J. Williams +3
We present the in-plane optical reflectance measurement on single crystals of URuAs. The study revealed a strong temperature-dependent spectral evolution. Above 50 K, the l…
Revealing the dual nature of magnetism in iron pnictides and iron chalcogenides using x-ray emission spectroscopy
H. Gretarsson, A. Lupascu, Jungho Kim +18
We report Fe K beta x-ray emission spectroscopy study of local magnetic moments in various iron based superconductors in their paramagnetic phases. Local magnetic moments are found…
High energy pseudogap and its evolution with doping in Fe-based superconductors as revealed by optical spectroscopy
N. L. Wang, W. Z. Hu, Z. G. Chen +4
We report optical spectroscopic measurements on electron- and hole-doped BaFe2As2. We show that the compounds in the normal state are not simple metals. The optical conductivity sp…
Infrared spectrum and its implications for the electronic structure of the semiconducting iron selenide KFeSe
Z. G. Chen, R. H. Yuan, T. Dong +7
We report an infrared spectroscopy study on KFeSe, a semiconducting parent compound of the new iron-selenide system. The major spectral features are found to…
Three dimensionality of band structure and a large residual quasiparticle population in BaKFeAs as revealed by the c-axis polarized optical measurement
B. Cheng, Z. G. Chen, C. L. Zhang +10
We report on a c-axis polarized optical measurement on a BaKFeAs single crystal. We find that the c-axis optical response is significantly different from…
Formation of partial energy gap below the structural phase transition and the rare-earth element substitution effect on infrared phonons in ReFeAsO (Re=La, Nd, and Sm)
T. Dong, Z. G. Chen, R. H. Yuan +3
Single crystals of LaFeAsO, NdFeAsO, and SmFeAsO have been prepared by means of a NaAs flux growth technique and studied by optical spectroscopy measurements. We show that the spec…
Optical spectroscopy study on single crystalline LaFeAsO
Z. G. Chen, R. H. Yuan, T. Dong +1
Millimeter-sized single crystals of LaFeAsO were grown from NaAs flux and the in-plane optical properties were studied over a wide frequency range. A sizable electronic correlation…
