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
