Correlated Weyl Fermions in Oxides

Abstract

Weyl fermions in magnetic oxides offer an ideal laboratory to study their two novel aspects, i.e., (i) the spin-momentum locking, and (ii) the diverging Berry curvature of magnetic monopole in momentum space. Here two representative examples are reviewed; the anomalous Hall effect and spin wave dynamics in SrRuO 3 , and the various Weyl semimetal phases in pyrocholore oxides.
