  We theoretically study the anisotropic magnetotransport in Dirac-Weyl
magnetic junctions where a doped ferromagnetic Weyl semimetal is sandwiched
between doped Dirac semimetals. We calculate the conductance using the Landauer
formula and find that the system exhibits extraordinarily large anisotropic
magnetoresistance (AMR). The AMR depends on the ratio of the Fermi energy and
the strength of the exchange interaction. The origin of the AMR is the shift of
the Fermi surface in the Weyl semimetal and the mechanism is completely
different from the conventional AMR originating from the spin dependent
scattering and the spin-orbit interaction.
