Abstract: We present a specific heat and resistivity study of CeIrIn5 in magnetic fields up to 17 T and temperature down to 50 mK. Both quantities were measured with the magnetic field parallel to the c axis (Hparallel to[001]) and within the a-b plane (Hperpendicular to[001]). Non-Fermi-liquid (NFL) behavior develops above 12 T for Hparallel to[001]. The Fermi-liquid state is much more robust for Hparallel to[001] and is suppressed only moderately at the highest applied field. Based on the observed trends and the proximity to a metamagnetic phase transition, which exists at fields above 25 T for Hparallel to[001], we suggest that the observed NFL behavior in CeIrIn5 is a consequence of a metamagnetic quantum critical point.
