Abstract

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 < p_c)and paramagnetic states (p > p_c). The observed Fermi surface, mass enhancement and scattering mechanism are highly different in these states.
