Control of Correlations in Sr4V2O6Fe2As2 by Chemical Stoichiometry
Athena S. Sefat, David J. Singh, V. Ovidiu Garlea +4
We show using a combination of powder X-ray and neutron diffraction, first principles calculations, temperature- and field-dependent magnetization, heat capacity and resistivity da…
Competing magnetic ground states in non-superconducting Ba(Fe1-xCrx)2As2
K. Marty, A. D. Christianson, C. H. Wang +7
We present neutron diffraction measurements on single crystal samples of non-superconducting Ba(Fe1-xCrx)2As2 as a function of Cr-doping for 0<=x<=0.47. The average SDW moment is i…
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…
Hole-doped BaFe2-xCrxAs2 Crystals: A Case of Non-superconductivity
Athena S. Sefat, David J. Singh, Lindsay H. VanBebber +6
We investigate the physical properties and electronic structure upon Cr-doping in the iron arsenide layers of BaFe2As2. This form of hole-doping leads to suppression of the magneti…
Itinerant antiferromagnetism in BaCrAs
D. J. Singh, A. S. Sefat, M. A. McGuire +4
We report single crystal synthesis, specific heat and resistivity measurements and electronic structure calculations for BaCrAs. This material is a metal with itinerant ant…
