摘要：

We performed de Haas -van Alphen (dHvA) experiments in the spintriplet superconductor UTe2 for magnetic field along the c-axis above 15 T. Three fundamental dHvA frequencies, named alpha 1, alpha 2, and ss corresponding to the cross sections of cylindrical Fermi surfaces (FSs) with large cyclotron effective masses (33 - 43(m0)) were detected. No other fundamental dHvA frequencies were detected at high frequency range, suggesting a cylindricalshaped electron FS without connecting at the Z point of the Brillouin zone. However, the existence of small pocket FSs associated with extremely heavy masses cannot be fully excluded.
