Computational search for magnetic Weyl semimetals in rare-earth compounds*

Weyl fermions are of interests for both basic science and future technology. Weyl points in electronic band structure can be generated by breaking inversion or/and time-reversal symmetry to realize linear crossings having monopoles of Berry curvature. Here we have used high throughput band structure calculations based on density functional theory to search for magnetic Weyl semimetals in rare-earth compounds. The existence of Weyl points is identified by calculating Berry curvature. We find that the magnetic Weyl points depend on the specific magnetic ordering structure.
