Résumé

We show that in recently discovered heavy fermion superconductors, quasi two-dimensional CeCoIn₅ and skutterudite PrOs₄Sb ₁₂, multiple superconducting phases with different symmetries manifest themselves below T_c. The ultrasound velocity measurements revealed that in CeCoIn₅ the Fulde-Ferrel-Larkin-Ovchinikov phase, in which the order parameter is spatially modulated and has planar nodes aligned perpendicular to the vortices, appears at low temperature and high field. The angle resolved magnetothermal transport measurements revealed that in PrOs ₄Sb₁₂ a novel change in the symmetry of the superconducting gap function occurs deep inside the superconducting state. These results open up a new realm for the study of the superconductivity with multiple phases.
