✦ Synopsis

The magnetic properties of Cu(NH-&(NO-&

have been measured at low temperatures. Broad maxima in both the susceptibility and specific heat are observed and are consistent with linear chain behavior of a Heiscnberg antifcrromagnct, with J/k = -3.9 * 0.1 K. Long-range order sets in at Tc = 0.15 + 0.01 K, and the ratio kTdlJI = 0.038 is the lowest observed as yet for a one-dimensional, S = l/2 antifcrromagnct.
