Abstract

We present an analysis of the normal-state magnetotransport in the heavy-fermion superconductor CeIrIn5. The Hall effect and the transverse magnetoresistance in this material do not appear to be uniquely correlated, as inferred from the field dependence of the current ratio (R-sigma = sigma(xy)/sigma(xy)/sigma(2)(xx) H). The Hall coefficient is seen to satisfy a scaling equation of the form R-H = f [H/(a + bT(c))]. These results are compared to those observed earlier in CeCoIn5, and are discussed in terms of the contrasting phase diagram which the CeIrIn5 system exhibits in relation to its Co counterpart.
