Unconventional Magnetic Behavior in Multicomponent Compounds

[摘要] This funding supported investigations of the behavior of complex materials. Very often the chosen materials were structurally complex, since in such cases more and new degrees of freedom that lead to more complicated interactions and more variable behavior. We summarize the most successful parts of that research: (1) implementation of Wannier functions to obtain magnetic coupling constants in magnetic insulators; (2) quasiparticle (single-particle excitation) studies of LiH under high pressure; (3) time-dependent density functional theory applied to study energy loss processes in superconducting MgB2.
