Spin correlations and cobalt charge states: A new phase diagram of sodium cobaltates
G. Lang, J. Bobroff, H. Alloul +2
Using 23Na NMR measurements on sodium cobaltates at intermediate dopings (0.44<=x<=0.62), we establish the qualitative change of behavior of the local magnetic susceptibility at x*…

Na atomic order, Co charge disproportionation and magnetism in NaCoO for large Na contents
H. Alloul, I. R. Mukhamedshin, G. Collin +1
We have synthesized and characterized four different stable phases of Na ordered NaCoO, for . Above 100 K they display similar Curie-Weiss susceptibilities…

Evidence of a single nonmagnetic Co3+ state in the Na1CoO2 cobaltate
G. Lang, J. Bobroff, H. Alloul +3
Macroscopic magnetization, muon spin rotation (muSR), and NMR measurements were carried out to study magnetism in the Na1CoO2 cobaltate. Using SQUID measurements, Na1CoO2 is shown…
