Abstract

Fermi surface properties of various uranium-based intermetallic compounds, including a 5f-localized compound, Pauli paramagnets, heavy fermions, antiferromagnets and ferromagnets, have been investigated by means of the de Haas-van Alphen effect. For this purpose we have grown high-quality single crystals using a purified uranium metal. Both the topology of the Fermi surface and the cyclotron mass in Pauli paramagnets such as USi3 are well explained by the band calculations. Surprisingly, the topology of the Fermi surface in heavy fermions such as UPt3 and UPd2Al3 also agree with the theoretical calculations, except for their unusually large mass enhancement. We have also succeeded in detecting a dHvA oscillation in the superconducting mixed state in the heavy fermion superconductor, UPd2Al3. Spin-polarized band calculatioins are approximately applicable to some magnetically ordered compounds such as UBi2 and UNiGa5.
