N2 - 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.
