Abstract

The low-field susceptibility,1 specific heat,2 proton resonance,3 and magnetization isotherms4 of Cu(NO3)2 · 2.5H2O at low temperatures can be described approximately by a model in which the cupric ions are antiferromagnetically coupled in pairs. The members of a pair (S1 = S2 = \(\frac{1}{2}\)) are assumed to interact via isotropic exchange J1S1·S2 with J1/k = 5.2°K. Quantitative discrepancies between this simple model and the data were removed initially by including a weaker antiferromagnetic interpair coupling in a molecular-field approximation.4
