Abstract
Using /sup 23/Na NMR measurements on sodium cobaltates at intermediate dopings (0.44
x*. It is suggested that at a given x the ferromagnetic correlations might dominate the antiferromagnetic ones above T*. From /sup 59/Co NMR data, it is shown that moving toward higher x away from x=0.5 results in the progressive appearance of nonmagnetic Co/sup 3+/ sites, breaking the homogeneity of Co states encountered for x
