Spins of relativistic fermions are related to their orbital degrees of freedom. In order to quantify the relativistic effect in systems composed of both relativistic and nonrelativistic fermions, we focus on the spin-orbital (SO) crossed susceptibility, which becomes finite in the presence of spin-orbit coupling. The SO crossed susceptibility is defined as the response function of their spin polarization to the "orbital" magnetic field, namely the effect of magnetic field on the orbital motion… Expand

Evidence for magnetic Weyl fermions in a correlated metal.
TLDR
Experimental evidence is reported for magnetic Weyl fermions in Mn3Sn, a non-collinear antiferromagnet that exhibits a large anomalous Hall effect, even at room temperature, and lays the foundation for a new field of science and technology involving the magnetic Wey excitations of strongly correlated electron systems such as Mn3 Sn.
