Abstract
A qualitative difference has been found between the temperature depend ence of the rate of spin relaxation of sodium nuclei in a NaxWO3 sampl e with a superconducting composition (x=0.2) and that in a sample with a nonsuperconducting composition (x=0.4). The difference is attribute d to antiferromagnetic correlations in the conduction band of the samp le with a superconducting composition.
