Abstract

We report on the evolution of the Hall effect in heavy fermion compounds CeMIn₅ (M=Co, Rh), ranging from antiferromagnetic metal to Fermi liquid regime through non-Fermi liquid regime by applying pressure. We found that anomalous transport properties of CeMIn₅ are strikingly similar to that of high-T_c cuprates. We also found that the magnitude of Hall coefficient appears to diverge near an antiferromagnetic quantum critical point. These results strongly suggest that unusual transport properties of CeMIn₅ are dominated by anisotropic scattering due to strong spin fluctuations.
