Observation of Dirac Cone Electronic Dispersion in BaFe2As2
P. Richard, K. Nakayama, T. Sato +8
We performed an angle-resolved photoemission spectroscopy study of BaFe2As2, which is the parent compound of the so-called 122 phase of the iron-pnictide high-temperature supercond…
Fermi surface topology and low-lying quasiparticle dynamics of parent FeTe/Se Superconductor by orbital-polarization resolved ARPES
Y. Xia, D. Qian, L. Wray +5
We report the first photoemission study of FeTe - the host compound of the newly discovered iron-chalcogenide superconductors (maximum T 27K). Our results reveal…
Origin of the structural phase transition at 130 K in BaNiAs: a combined study of optical spectroscopy and band structure calculations
Z. G. Chen, G. Xu, W. Z. Hu +6
BaNiAs exhibits a first order structural transition at 130 K. Understanding this structural transition is a crucial step towards understanding the electronic properties of…
Structural and magnetic phase transitions in NaFeAs
Shiliang Li, Clarina de la Cruz, Q. Huang +5
We use neutron scattering to study the spin and lattice structures of single crystal and powder samples of NaFeAs ( K). On cooling from room temperature, the syst…
Fermi surface dichotomy of the superconducting gap and pseudogap in underdoped pnictides
Y. -M. Xu, P. Richard, K. Nakayama +15
High-temperature superconductivity in iron-arsenic materials (pnictides) near an antiferromagnetic phase raises the possibility of spin-fluctuation-mediated pairing. However, the i…
Possible high temperature superconductivity in Ti-doped A-Sc-Fe-As-O (A= Ca, Sr) system
G. F. Chen, T. -L. Xia, H. X. Yang +4
We report a systematic study on the effect of partial substitution of Sc by Ti in SrScFeAsO, CaScFeAsO and SrScFeAsO$_…
