The nuclear relaxation rate 1 T1 of 11B in antiferromagnets PrB6 and NdB6 has been measured in the paramagnetic states. 1 T1 shows critical divergence with 1 T1∝ [(T - TN) TN]-0.20. At higher temperatures, the correlation time of the 4f moments deduced from T1 is considered to be dominated by the interactions between conduction and 4f electrons.
