Abstract

We have grown 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/cosθ-dependence, revealing the presence of cylindrical Fermi surfaces, where θ is a tilt angle from [001] to [100].The cyclotron masses are in the range from 1.84 to 8.33, m₀.The two-dimensional Fermi surfaces are due to the conduction electrons in the U-plane, including the itinerant 5f /-electrons.
