Abstract

The heavy Fermion superconductor Ce3PtIn11 first goes two consequent antiferromagnetic transitions at 2.3 and 2.1 K and eventually becomes superconducting at 0.3 K. A first muSR experiment on this compound showed the presence of static internal fields in the antiferromagnetic phase which persists into the superconducting state. However, they the internal field disappears at the very lowest temperatures. Ce3PtIn11 could thus serve as a model system to study the interplay between magnetism and superconductivity, which are normally antagonistic.
