Abstract

We carried out the de Haas-van Alphen (dHvA) experiment under pressure to clarify the nature of f-electron compounds of CeRh₂Si₂, UGe₂ and CeCoIn₅. With increasing pressure, the Néel temperature T_N = 36 K in CeRh₂Si₂ and the Curie temperature T_C = 52 K in UGe₂ decrease, and a quantum critical point corresponding to the extrapolation T_N or T_C → 0 is reached at the critical pressure p_c ≃ 1.06 and 1.52 GPa, respectively. Experimental results indicate a discontinuous change of the Fermi surface in CeRh₂Si₂ and UGe₂ when the pressure crosses p_c. A heavy fermion superconductor CeCoIn₅ with a quasi-two dimensional Fermi surface was found to be located in the vicinity of the quantum critical point.
