Abstract:
Materials with one-dimensional Weyl nodal lines are attracting much attention because of rich exotic properties. In this work, based on the first-principles calculations, we predict the existence of Weyl nodal lines in Fe70Al30. A large intrinsic anomalous Hall conductivity is calculated to be −374 S/cm, which stems from the net Berry curvature induced by Weyl nodal lines. To confirm our calculated results, high quality Fe70Al30 has been prepared and did possess a large anomalous Hall conductivity, where the intrinsic Berry curvature plays a role.
