Interplay between magnetism and sodium vacancy ordering in NaxCoO2
Stanislaw Galeski, Kurt Mattenberger, Bertram Batlogg
Using a combination of low-temperature nanocalorimetry and x-ray diffraction we identify three temperature regimes characterized by distinct Na ordering patterns (low temperature u…
Spin fluctuations, magnetic long-range order and Fermi surface gapping in NaxCoO2
T. F. Schulze, M. Bruehwiler, P. S. Haefliger +5
In this study an extended low energy phase diagram for NaxCoO2 is experimentally established with emphasis on the high x range. It is based on systematic heat capacity studies on b…
Melting of the Na layers in solid Na0.8CoO2
M. Weller, A. Sacchetti, H. R. Ott +2
Data of 23Na NMR spectra- and relaxation measurements are interpreted as suggesting that, upon increasing temperature the Na layers in Na0.8CoO2 adopt a 2D liquid state at T=291 K.…
Direct link between low temperature magnetism and high temperature sodium order in NaxCoO2
T. F. Schulze, P. S. Häfliger, C. Niedermayer +3
We prove the direct link between low temperature magnetism and high temperature sodium ordering in NaxCoO2 using the example of a heretofore unreported magnetic transition at 8 K w…
