Abstract

We have measured the magnetoresistance and de Haas-van Alphen (dHvA) effect in the ferromagnetic compound UGe₂. It is found that UGe₂ is a compensated metal whose Fermi surface supports open orbits, along the b- and c-axes of the orthorhombic crystal structure. From the dHvA experiment, we have detected carriers with heavy cyclotron masses, ranging from 2.3m₀ to 24.5m₀.
