Abstract

We have studied de Hass van Alphen (dHvA) effect under pressure for a pressure-induced superconductor CeRhIn₅ and a superconductor CeCoIn₅. The topology of the Fermi surface in CeRhIn₅ and CeCoIn₅ are found to be unchanged up to 2.1 GPa and 3.1 GPa, respectively. On the other hand, the effective mass of CeRhIn ₅(CeCoIn₅) decreases (increases) remarkably with increasing pressure.
