Temperature and Pressure Dependence of the Fe-specific Phonon Density of States in Ba(Fe(1-x)Co(x))2As2
O. Delaire, M. S. Lucas, A. M. dos Santos +15
The {57}Fe-specific phonon density of states of Ba(Fe(1-x)Co(x))2As2 single crystals (x=0.0, 0.08) was measured at cryogenic temperatures and at high pressures with nuclear-resonan…
Effects of nematic fluctuations on the elastic properties of iron arsenide superconductors
Rafael M. Fernandes, Lindsay H. VanBebber, Shobo Bhattacharya +7
We demonstrate that the changes in the elastic properties of the FeAs systems, as seen in our resonant ultrasound spectroscopy data, can be naturally understood in terms of fluctua…
Superconductivity Near a Quantum Critical Point in Ba(Fe,Co)2As2
K. Ahilan, F. L. Ning, T. Imai +7
We will examine the possible link between spin fluctuations and the superconducting mechanism in the iron-based high temperature superconductor Ba(Fe,Co)2As2 based on NMR and high…
A Model of the Normal State Susceptibility and Transport Properties of Ba (Fe1-xCox)2As2: An Explanation of the Increase of Magnetic Susceptibility with Temperature
B. C. Sales, M. A. McGuire, A. S. Sefat +1
A simple two-band model is used to describe the magnitude and temperature dependence of the magnetic susceptibility, Hall coefficient and Seebeck data from undoped and Co doped BaF…
Phonons as a probe of the magnetic state in doped and undoped BaFe2As2
D. Reznik, K. Lokshin, D. C. Mitchell +17
We measured phonon frequencies and linewidths in doped and undoped BaFe2As2 single crystals by inelastic x-ray scattering and compared our results with density functional theory (D…
Anisotropic thermal expansion of Fe1.06Te and FeTe0.5Se0.5 single crystals
S. L. Bud'ko, P. C. Canfield, A. S. Sefat +3
Heat capacity and anisotropic thermal expansion was measured for Fe1.06Te and FeTe0.5Se0.5 single crystals. Previously reported phase transitions are clearly seen in both measureme…
