Magnetic peculiarities of plutonium and compounds

The problems concerning the peculiarities of plutonium crystal structures, their distinguishing features from the structures of common metals are discussed in the paper. They are found to be in close interdependence with the intricate problem of localized magnetic moments and magnetic ordering in plutonium and its numerous compounds. Multifarious physical models suggested for determining the nature and origins of these peculiar features, based on the well-known concepts and approaches and also on novel very original and exotic ideas, are considered. The detailed comparative analysis of experimental achievements and numerous papers in various versions of numerical computations in “the first principles (ab initio)” approach is carried out. Some new effects recently discovered and not as yet comprehended are regarded as well.
