N2 - We succeeded in growing high-quality single crystals of UX 2 (X = Bi, Sb, As or P) by the self-flux and chemical transport methods and carried out de Haasvan Alphen and Shubnikov-de Haas experiments. We found quasi-two-dimensional Fermi surfaces in these U compounds. Fermi surfaces of UBi 2 are found to consist of one spherical Fermi surface and two cylindrical Fermi surfaces. Each Fermi surface in UBi 2 changes into two cylindrical surfaces in USb 2 and UAs 2 . This change in the Fermi surfaces is well explained on the basis of a fiat magnetic Brillouin zone. The quasi-two-dimensional character of the Fermi surfaces is mainly due to the conduction electrons in the U piane, including the 5f electrons. The itinerant nature of 5f electrons is reflected in the large cyclotron masses. The magnetic breakthrough (breakdown) phenomenon is also discussed for USb 2 .
