摘要：
We have gown high-quality single crystals of tetragonal USb2 using a flux method. We have detected five branches in de Haas-van Alphen (dHvA) experiments. Frequencies of all dHvA branches follow the 1/cos theta-dependence, revealing the presence of cylindrical Fermi surfaces, where theta is a tilt angle from [001] to [100]. The cyclotron masses are in the range from 1.84 to 8.33 m(0). The two-dimensional Fermi surfaces are due to the conduction electrons in the U-plane, including the itinerant 5f-electrons.
