We carried out the de Haas-van Alphen experiment under pressure for a heavy fermion antiferromagnet URu2Si2-The detected cyclotron mass for a nearly spherical Fermi surface under pressure changes considerably, reflecting a change of the magnetic moment. The present result is, however, inconsistent with the recent phase separated proposal.
