The heavy fermion systems of the class CeMIn5 (with M=Co, Ir or Rh)
have proven to be a fertile playground for unravelling the complex interplay between
magnetism and unconventional superconductivity. The interest in these systems has also been fuelled by the remarkable similarity of some of  the superconducting and normal state properties of these materials, with the high temperature superconducting cuprates. The insight gained into the low temperature phase diagram of one of these systems (CeIrIn5) using sensitive Hall effect and magnetoresistance measurements will be described. A striking observation pertains to the presence of a precursor state - characterized by a change in the Hall mobility - to the superconductivity in this system, in similarity to the pseudogap in the cuprate superconductors.
