Abstract
We report measurements of the de Haas-van Alphen effect in UGe2 under hydrostatic pressures up to 17.6 kbar, exceeding the critical pressure Pc for the suppression of ferromagnetism. A discontinuous change of the Fermi surface is found to occur across Pc. Substantially enhanced effective masses (∼40me) are found near Pc on both the ferromagnetic and the paramagnetic sides.
