Spin dynamics in the pseudogap state of a high-temperature superconductor
V. Hinkov, P. Bourges, S. Pailhes +7
The pseudogap is one of the most pervasive phenomena of high temperature superconductors. It is attributed either to incoherent Cooper pairing setting in above the superconducting…
Doping induced magnetic clusters and Co spin state transition in Na_xCoO_2 with 0.78<x<.97
C. Bernhard, Ch. Niedermayer, A. Drew +7
By muon spin rotation we investigated the magnetic properties of a series of highly Na doped NaxCoO2 single crystals with 0.78(1)<x<0.97(1). Our data provide evidence for an intrin…
Spin singlet pairing in the superconducting state of NaxCoO2\cdot1.3H2O: evidence from a ^{59}Co Knight shift in a single crystal
Guo-qing Zheng, Kazuaki Matano, D. P. Chen +1
We report a ^{59}Co Knight shift measurement in a single crystal of the cobalt oxide superconductor Na_{x}CoO_2\cdot1.3H_2O (T_c=4.25 K). We find that the shift due to the spin sus…
The crystal growth and characterization of NaxCoO2 and NaxCoO2yH2O
D. P. Chen, H. C. Chen, A. Maljuk +4
A systematic study of NaxCoO2 (x=0.50 - 0.90) and NaxCoO2 yH(D)2O (x=0.26 - 0.42, y=1.3) has been performed to determine phase stability and the effect of hydration on the structur…
