Noncollinear spin and orbital magnetism in actinide compounds: Effects of symmetry and relativity

Abstract

The density functional theory is applied to study the nature of complex magnetic structures in various Uranium compounds: U2Pd2Sn, U3X4, UPdSn, UX3, UPdSn and UPtGe. A general approach isdeveloped which allows to treat principally different magnetic states of these compounds on the basis of one physical concept. This concept relates the strong spin-orbit coupling in the U systems and the symmetry of the crystal and magneticstructures to the stability of the magnetic configurations. © 2014 Taylor and Francis Group, LLC.
