  "abstract": "The antiferromagnetic semiconductor CuFeS$_2$ belongs to a magnetic symmetry class that is of interest for spintronics applications. In addition, its crystal lattice is compatible with Si, making it possible to integrate it with non-magnetic semiconducting structures. Therefore, we investigate this material by finding the effective $\\boldsymbol{k}\\cdot\\boldsymbol{p}$ Hamiltonian for the electron- and hole bands. We base this description on \\textit{ab initio} calculations and classify the electronic bands by their symmetry. As a result, we find that CuFeS$_2$ exhibits spin-polarized bands and an anomalous Hall effect. Finally, we suggest using cyclotron resonance to verify our proposed effective mass tensors at the conduction band minimum and valence band maximum.",
