Observation of two-dimensional Fermi surface and Dirac dispersion in YbMnSb${}_2$

Abstract

We present the crystal structure, electronic structure, and transport properties of the material YbMnSb${}_2$, a candidate system for the investigation of Dirac physics in the presence of magnetic order. Our measurements reveal that this system is a low-carrier-density semimetal with a 2D Fermi surface arising from a Dirac dispersion, consistent with the predictions of density functional theory calculations of the antiferromagnetic system. The low temperature resistivity is very large, suggesting scattering in this system is highly efficient at dissipating momentum despite its Dirac-like nature.
