Magnetoresistance and de Haas-van Alphen Effect in CeIn₃

Abstract

We have measured the transverse magnetoresistance and de Haas-van Alphen (dHvA) effect in the antiferromagnetic Kondo substance CeIn₃. The magnetoresistance increases in all field directions, suggesting that this compound is a compensated metal. We have detected one dHvA branch which corresponds to the electron Fermi surface in the sixth band of LaIn₃, centered at the Γ point. The dHvA frequencies (cyclotron masses) at the ⟨100⟩ and ⟨111⟩ directions are 3.20×10⁷ Oe (2.02m₀) and 2.95×10⁷ Oe (2.88m₀), respectively.
