Abstract:

The calculations of electronic density of states, exchange-enhanced spin and orbital magnetic susceptibility of plutonium in its delta-phaze existing region are performed in terms of a generalized s(p)df-model, which enables to take the intra-site Hubbard ff-, dd-interactions and inter-site df-exchange interaction into account along with s,p,f and d-electrons band movement and orbital splitting of f-sates. It is shown that the splitting of the electronic spectra induced by fluctuating exchange fields leads to appearing of the temperature-induced local magnetic moments, to changing of d,f-bands occupation numbers with temperature and to appearing of charge fluctuations induced by spin fluctuations. A good agreement with the experimental data on temperature dependencies of magnetic susceptibility of Pu(0.95)Ga(0.05) and Pu(0.957)Ga(0.043) alloys is obtained.
