| Popis: | The recent PNAS paper by Migliori et al. (1) attempts to explain the unusually strong temperature dependence of the bulk modulus of fcc plutonium (δ-Pu) by use of the disordered local moment (DLM) model. It is our opinion that this approach does not correctly incorporate the dynamic magnetism of δ-Pu. First, we note that, contrary to the comments in Migliori et al. (1), the results of our recent inelastic neutron experiments (2) do not contradict the results of earlier experiments (3⇓–5), which show that the ground state is nonmagnetic. All of these experiments are consistent with the interpretation that δ-Pu has a nonmagnetic fluctuating valence ground state. … [↵][1]1To whom correspondence should be addressed.
