Fermi surfaces (FSs) of the anomalous UTe were successfully detected using quantum oscillation technique on an ultrapure single crystal. The shape of FS was reproduced from the experimental data revealing two cylindrical quasi-two-dimensional FSs. This analysis suggests that a fairly strong nesting nature possibly leading to magnetic fluctuations responsible for the triplet superconductivity.
