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 T_N=10 K decreases and becomes zero at a critical pressure P_c\\simeq2.6 GPa. In the pressure region P>P_c, 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 P_c, as observed in the similar antiferromagnets CeRh₂Si₂ and CeRhIn₅. The cyclotron effective mass m_c^∗ of this main Fermi surface is extremely enhanced around P_c: m_c^∗\\simeq60m₀ at 2.7 GPa for the magnetic field along the ⟨100⟩ direction.
