EN

The interaction of spins localized within the band-inverted heterojunction with the Weyl excitations is shown to differ significantly from the usual s-d interaction. The indirect exchange interaction is long-range and anti-ferromagnetic. The magnitude of interaction decreases with the distance as R^{-3}. The effective interaction depends on the parameters of electron energy spectrum and parameters of the heterojunction as well. It consists of anisotropic Heisenberg term and of pseudodipole terms.
