We report resistivity ρ and Hall effect measurements on EuFe₂As₂ at ambient pressure and 28 kbar and magnetization measurements at ambient pressure. We analyze the temperature and magnetic-field dependence of ρ and the Hall effect using a molecular-field theory for magnetoresistance and an empirical formula for the anomalous Hall effect and find that electron scattering due to the Eu²⁺ local moments plays only a minor role in determining electronic transport properties of EuFe₂As₂.
