Electromagnetic response of LaO_0.94F_0.06FeAs: AC susceptibility and microwave surface resistance
A. Agliolo Gallitto, G. Bonsignore, M. Bonura +3
We discuss on the electromagnetic response of a polycrystalline sample of LaO_0.94F_0.06FeAs exposed to DC magnetic fields up to 10 kOe. The low- and high-frequency responses have…
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…
Optical study on the spin-density wave properties in single crystalline NaFeAs
W. Z. Hu, G. Li, P. Zheng +3
We report an optical investigation on the in-plane charge dynamics for NaFeAs single crystal. A clear optical evidence for the spin-density wave (SDW) gap is observed. As t…
Band-dependent Quasiparticle Dynamics in Single Crystals of the BaKFeAs Superconductor Revealed by Pump-Probe Spectroscopy
Darius H Torchinsky, G. F. Chen, J. L. Luo +2
We report on band-dependent quasiparticle dynamics in BaKFeAs () measured using ultrafast pump-probe spectroscopy. In the superconducting state,…
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$_…
Multiple phase transitions in single-crystalline NaFeAs
G. F. Chen, W. Z. Hu, J. L. Luo +1
Specific heat, resistivity, susceptibility and Hall coefficient measurements were performed on high-quality single crystalline NaFeAs. This compound is found to undergo thr…
