      abstract     = {We investigate rare-earth magnetic Weyl semimetals through
                      first-principles simulations, analyzing the connection
                      between incommensurate magnetic order and the presence of
                      Weyl nodes in the electronic band structure. Focusing on
                      PrAlSi, NdAlSi, and SmAlSi, we demonstrate that the reported
                      helical ordering does not originate from the nesting of
                      topological features at the Fermi surface or the
                      Dzyaloshinskii-Moriya interaction. Instead, the helical
                      order arises from frustrated isotropic short-range
                      superexchange between the 4f moments facilitated by pd
                      hybridization with the main group elements. Employing a spin
                      Hamiltonian with isotropic exchange and single-ion
                      anisotropy we replicate the experimentally observed helical
                      modulation.},
