NMR Search for the Spin Nematic State in LaFeAsO Single Crystal
M. Fu, D. A. Torchetti, T. Imai +3
We report a 75-As single crystal NMR investigation of LaFeAsO, the parent phase of a pnictide high Tc superconductor. We demonstrate that spin dynamics develop a strong two-fold an…
NMR Characterization of Sulphur Substitution Effects in the K(x)Fe(2-y)Se(2-z)S(z) high Tc Superconductor
D. A. Torchetti, T. Imai, H. C. Lei +1
We present an NMR study of the effect of S substitution in the high Tc superconductor K(x)Fe(2-y)Se(2-z)S(z) in a temperature range up to 250 K. We present NMR Knight shift and nuc…
Effect of annealing on the specific heat of Ba(Fe1-xCox)2As2
K. Gofryk, A. B. Vorontsov, I. Vekhter +5
We report on the effect of annealing on the temperature and field dependencies of the low temperature specific heat of the electron-doped Ba(FeCo)As for u…
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…
The Electronic Phase Diagram of the Iron-based High Tc Superconductor Ba(Fe(1-x)Co(x))2As2 Under Hydrostatic Pressure (0 < x <0.099)
K. Ahilan, F. L. Ning, T. Imai +4
We report comprehensive resistivity measurements of single crystalline samples of the Ba(Fe(1-x)Co(x))2As2 high Tc superconductor under hydrostatic pressure up to 2.75 GPa and over…
