On the origin of the electronic anisotropy in iron pnicitde superconductors
W. -L. Zhang, P. Richard, H. Ding +5
We use polarization-resolved Raman spectroscopy to study the anisotropy of the electronic characteristics of the iron-pnictide parent compounds FeAs (~=~Eu, Sr).…
Raman scattering investigation of the electron-phonon coupling in superconducting Nd(O,F)BiS
S. F. Wu, P. Richard, X. B. Wang +5
We have performed polarized Raman scattering measurements on the newly discovered superconductor Nd(O,F)BiS ( K). We observe 2 Raman active modes, with frequencies in…
Raman scattering investigation of superconducting BaTiFeAsO
S. -F. Wu, P. Richard, W. -L. Zhang +5
We have performed polarized Raman scattering measurements on the newly discovered superconductor BaTiFeAsO ( K). We observe seven out of eig…
Observation of anomalous temperature dependence of spectrum on small Fermi surfaces in a BiS2-based superconductor
L. K. Zeng, X. B. Wang, J. Ma +7
We performed an angle-resolved photoemission spectroscopy study of the BiS2-based superconductor Nd(O,F)BiS2. Two small electron-like Fermi surfaces around X (pi, 0) are observed,…
