Temperature-dependent resistivity ρ(T) and magnetoresistance are measured in bulk tetragonal phase of antiferromagneticCuMnAsandarefoundtobeanisotropicbothduetostructureandmagneticorder.Wecompare these findings to model calculations with chemical disorder and finite-temperature phenomena included. The finite-temperature ab initio calculations are based on the alloy analogy model implemented within the coherent potential approximation and the results are in fair agreement with experimental data.
