The temperature dependent magnetic susceptibility, {chi}(T), of two samples of the S = 1 linear-chain Heisenberg antiferromagnet Ni(C{sub 2}H{sub 8}N{sub 2}){sub 2}NO{sub 2}(ClO{sub 4}), known as NENP, has been measured from 400 K to 264 {mu}K. The authors measurements are in agreement with existing results of other researchers who worked above 1.2 K. Below 1.2 K, {chi}(T) increases with decreasing temperature. The results suggest that this increase is intrinsic to the NENP and is not a consequence of a single source of paramagnetic impurities in the samples. 14 refs., 3 figs.
