59-Co and 75-As NMR Investigation of Electron-Doped High Tc Superconductor BaFe(1.8)Co(0.2)As(2) (Tc = 22K)
F. L. Ning, K. Ahilan, T. Imai +5
We report an NMR investigation of the superconductivity in BaFe(2)As(2) induced by Co doping (Tc=22K). We demonstrate that Co atoms form an alloy with Fe atoms and donate carriers…
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…
^{59}Co NMR evidence for charge ordering below T_{CO}\sim 51 K in Na_{0.5}CoO_2
F. L. Ning, S. M. Golin, K. Ahilan +3
The CoO layers in sodium-cobaltates NaCoO may be viewed as a spin triangular-lattice doped with charge carriers. The underlying physics of the cobaltates…
Sodium vacancy ordering and the co-existence of localized spins and itinerant charges in NaxCoO2
F. C. Chou, M. -W. Chu, G. J. Shu +6
The sodium cobaltate family (NaxCoO2) is unique among transition metal oxides because the Co sits on a triangular lattice and its valence can be tuned over a wide range by varying…
