We present Hall effect and magnetoresistance measurements in the heavy fermion superconductor CeIrIn5. At low temperature, a Kondo coherent state is established. Deviations from Kohler's rule and a quadratic temperature dependence of the cotangent of the Hall angle are reminiscent of properties observed in the high-temperature superconducting cuprates. A striking observation pertains to the presence of a precursor state-characterized by a change in the Hall mobility-that precedes the superconductivity in this material, in similarity to the pseudogap in the cuprate superconductors. © 2008 The American Physical Society.
