Renormalized behavior and proximity to a magnetic quantum critical point in BaCoAs
A. S. Sefat, D. J. Singh, R. Jin +3
We report synthesis and single crystal measurements of magnetic, transport and thermal properties of single crystalline BaCoAs as well as first principles calculations of t…
C-axis Phonons in Fe-As Based Superconductors Investigated by Inelastic X-ray Scattering
D. Reznik, K. Lokshin, D. C. Mitchell +16
In Fe-As based superconductors magnetism and superconductivity show strong sensitivity to the lattice, suggesting a possibility of unconventional electron-phonon coupling. We inves…
Phonon Density of States of LaFeAsO1-xFx
A. D. Christianson, M. D. Lumsden, O. Delaire +16
We have studied the phonon density of states (PDOS) in LaFeAsO1-xFx with inelastic neutron scattering methods. The PDOS of the parent compound(x=0) is very similar to the PDOS of s…
Effect of pressure on the superconducting critical temperature of La[O_{0.89}F_{0.11}]FeAs and Ce[O_{0.88}F_{0.12}]FeAs
D. A. Zocco, J. J. Hamlin, R. E. Baumbach +9
We have performed several high-pressure resistivity experiments on the recently discovered superconductors La[O_{0.89}F_{0.11}]FeAs and Ce[O_{0.88}F_{0.12}]FeAs. At ambient pressur…
19-F NMR Investigation of Iron-pnictide Superconductor LaFeAsO(0.89)F(0.11)
K. Ahilan, F. L. Ning, T. Imai +5
We report 19-F NMR investigation of the new high temperature superconductor LaFeAsO(0.89)F(0.11) (Tc ~ 28K). We demonstrate that low frequency spin fluctuations exhibit pseudo gap…
