Abstract
We observed the de Has-van Alphen oscillation in the heavy fermion compound CeIrIn5. The topology of the Fermi surface is found to be nearly cylindric al, reflecting the unique tetragonal structure. Observed branches are well explained bg the 4f-itinerant band model. The cyclotron masses of 20-30m(0) are one order larger than the corresponding band masses.
