Abstract

We have studied a change of the Fermi surface in an antiferromagnet CeIn3 via the de Haas-van Alphen experiment under pressure up to 3 GPa. With increasing pressure P, the Néel temperature TN = 10 K decreases and becomes zero at a critical pressure Pc ≃ 2.6 GPa. In the pressure region P > Pc, we have observed a large main Fermi surface named a, which indicates that the electronic state of 4f electron in CeIn3 changes from localized to itinerant at Pc, as observed in the similar antiferromagnets CeRh2Si2 and CeRhIn5. The cyclotron effective mass mc* of this main Fermi surface is extremely enhanced around Pc: m c* ≃ 60m0 at 2.7 GPa for the magnetic field along the 〈100〉 direction.
