We observed de Haas-van Alphen (dHvA) oscillation in a paramagnetic plutonium compound, PuIn ₃ . In the present paper, we report the first observation of dHvA effect in plutonium compounds. One detected dHvA branch named γ corresponds to a closed band-27 electron Fermi surface, where three kinds of closed Fermi surfaces are calculated on the basis of the 5f -itinerant band model. The cyclotron mass of branch γ was determined as 4.8 m ₀ . The dHvA signals are found to be extremely reduced as a function of time due to point defects produced by α-decay of ²³⁹ Pu.
