Symmetry is a key to unlock exotic phenomena in condensed matter physics. Particularly in magnetic systems, the symmetry analysis enables deep understanding of magnetic ordering and electron transports. In this talk, I will give three examples showing how symmetry analysis can help understand and design magnetic materials of interest. First, I will show the prediction of giant perpendicular magnetic anisotropy (PMA) in iron monolayer on top of III-V nitride substrates. The magnitude of PMA is up to 50 meV, in contrast to 1meV in conventional Fe-based thin films.

The molecular-level description of the chemical bond between a solid surface and an atom or a molecule is the fundamental basis for understanding a broad range of scientific problems in heterogeneous catalysis, sensing, semiconductor device fabrication, fuel cells, anticorrosion, and tribology. Despite many decades of theoretical and experimental research in this area, what key physical factors and how they operate together in controlling the surface-adsorbate bonding strength remain elusive.
