Abstract

We have measured the magnetoresistance and de Hass-van Alphen oscillation of UC. The Fermi surface of semimetal UC is found to consist of three hole-ellipsoids located at the X points and six electron-ellipsoids at the W points in the fcc Brillouin zone. The cyclotron mass of electron at the ⟨110⟩ direction is 2.67m₀, which is heavy compared to that of hole, 0.84m₀.
