a Band structure near the Fermi energy calculated with spin–orbit coupling in the ferromagnetic ground state with the magnetic moment oriented along [110]o direction. We searched for Weyl nodes in four pairs of bands near the Fermi energy (pair I → green band and the one below; pair II → (green, red); pair III → (red, blue); pair IV → (blue, pink)). b The corresponding FS plot sliced along the k∥-kz plane, which indicates three major pockets of A–C. c Locations of Weyl nodes residing in these four pairs in the energy window of ∣E−EF∣ < 50 meV. The red and blue symbols are Weyl nodes with a chirality of +1 and −1, respectively. d The nonoverlapping Weyl-node pairs projected on k∥−kz plane. The arrows connect from +1 to −1 Weyl nodes at similar energy, where the calculated k0 values and the corresponding Weyl node energies in units of meV are indicated.
