Abstract

We grew a single crystal of UB₄ with the tetragonal structure and carried out the magnetoresistance and de Haas-van Alphen (dHvA) experiments. The magnetoresistance data indicate that UB₄, which is a compensated metal with equal carrier numbers of electrons and holes, most likely has open orbits along the [100] and [010] directions. We detected about eleven dHvA branches. The cyclotron masses are moderately heavy, ranging from 3.0 to 14.1 m₀, reflecting the electronic specific heat coefficient of 24.9 mJ/K²·mol.
