The electronic state in UGe2has been studied via the de Haas-van Alphen (dHvA) effect under hydrostatic pressure. The dHvA oscillation has been observed not only in the strongly polarized state (p < p* c) but also in the weakly polarized (p* c < p < pc)and paramagnetic states (p > pc). The observed Fermi surface, mass enhancement and scattering mechanism are highly different in these states.
