Robust magnetic order of Ce 4f-electrons coexisting with superconductivity in CeFeAsOF
T. Shang, L. Jiao, J. Dai +4
The electrical resistance of CeFeAsOF (x = 0.06 and 0.08) has been measured in a magnetic field up to 40T. At zero field, the sample with x = 0.06 shows a structural ph…
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…
Lattice distortion and magnetic quantum phase transition in CeFeAs(1-x)P(x)O
Clarina de la Cruz, W. Z. Hu, Shiliang Li +8
We use neutron scattering to show that replacing the larger arsenic with smaller phosphorus in CeFeAs(1-x)P(x)O simultaneously suppresses the AF order and orthorhombic distortion n…
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…
Optical and Raman spectroscopy studies on Fe-based superconductors
W. Z. Hu, Q. M. Zhang, N. L. Wang
A brief review of optical and Raman studies on the Fe-based superconductors is given, with special emphasis on the competing phenomenon in this system. Optical investigations on Re…
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…
