摘要
Magnetization measurements have been performed on NpFe2, PuFe2, and AmFe2 (cubic C15-type Laves phase) between 300 and 1100 K. The Curie temperatures were found to be 492 ± 2, 564 ± 2, and 613 ± 3 K, respectively. A correlation was found between the Curie temperature and the magnetic moment per iron atom determined in previous neutron-diffraction experiments. Critical exponents determined for NpFe2 and PuFe2 were found to be close to previously reported values for the chemically ordered metallic system Pd3Fe. The overall magnetic behavior of the compounds studied implies the presence of local magnetic moments, in contrast to the itinerant magnetic behavior of UFe2 noted in the previous paper. © 1979.
