On behalf of the DCMP and MGML


If in 3d systems the strongest magnetic interaction is the exchange interaction in the case of Uranium compounds the situation is more complex. Here the strong spin-orbit coupling enhances the magnetic anisotropy and Dzyaloshinskii-Moriya interaction making relative strength of various magnetic interactions system-dependent. In this talk I will discuss how different effective magnetic interactions between atomic moments appear in the first-principles calculations and can be extracted from calculated energies of various magnetic states. Then I consider examples of systems with principally different hierarchy of interactions and discuss the physical consequences of this difference.
