Strong pairing at iron orbitals in hole-doped BaFeAs
D. V. Evtushinsky, V. B. Zabolotnyy, T. K. Kim +14
Among numerous hypotheses, recently proposed to explain superconductivity in iron-based superconductors [1-9], many consider Fermi surface (FS) nesting [2, 4, 8, 10] and dimensiona…

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…

Contrasting Spin Dynamics Between Underdoped and Overdoped Ba(Fe[1-x]Co[x])2As2
F. L. Ning, K. Ahilan, T. Imai +7
We report the first NMR investigation of spin dynamics in the overdoped non-superconducting regime of Ba(Fe[1-x]Co[x])2As2 up to x =0.26. We demonstrate that the absence of inter-b…
