  The interplay of magnetism and unconventional superconductivity (d singlet
wave or p triplet wave) in 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 Tc oxide is briefly pointed out.
