Enthalpy of formation and magnetic susceptibility of curium sesquioxide, Cm2O3
Description
Monoclinic Cm2O3 has been prepared from the long-lived isotope 248Cm (t1/2 = 3.4 x 105 y), and its enthalpy of formation has been determined at 298 K to be -1682 +/- 12 kJ mol-1 from solution calorimetry measurements on four different samples. The magnetic susceptibility of three of these samples has been measured on a Faraday balance between 2 and 298 K. Cm2O3 exhibits Curie-Weiss behavior from 100 to 300 K with μ/sub eff/ = 7.89 +/- 0.04 μ/sub B/ and THETA = -130 +/- 2 K. The compound appears to order magnetically as the temperature decreases and has an antiferromagnetic transition at 13 +/- 2 K. The results are interpreted by comparison with similar properties of related lanthanide and actinide compounds
