Magnetism and Superconductivity of Heavy Fermion Matter
2006
Abstract The interplay of magnetism and unconventional superconductivity (d singlet wave or p triplet wave) in a strongly correlated electronic system (SCES) is discussed with recent examples found in heavy fermion compounds. A short presentation is given on the formation of the heavy quasiparticle with the two sources of a local and intersite enhancement for the effective mass. Two cases of the coexistence or repulsion of antiferromagnetism and superconductivity are given with CeIn3 and CeCoIn5. A spectacular example is the emergence of superconductivity in relatively strong itinerant ferromagnets UGe2 and URhGe. The impact of heavy fermion matter among other SCES as organic conductor or high T C oxide is briefly pointed out. To cite this article: J. Flouquet et al., C. R. Physique 7 (2006).
