Field dependence of low-temperature resistivity in CeIrIn5

We report on a study of the in-plane and inter-plane resistivity of the heavy-fermion superconductor CeIrIn$_{5}$. Measurements were performed down to 40 mK in a magnetic field applied parallel to the c axis. We analyze how the temperature dependence of the resistivity evolves with magnetic field, both inside and outside the Fermi-liquid regime, and compare this evolution with that of CeCoIn$_{5}$, a closely related material with a field-induced quantum critical point.
