| 概要 | We grew a single crystal of UB2 with the hexagonal structure and observed the de Haas-van Alphen (dHvA) oscillation. All of the dHvA branches, which are about seven in number. are detected in the limited angle regions. They are well explained by the 5f-itinerant relativistic band theory with an exchange and correlation potential in a local density approximation. Namely, UB2 is a compensated metal with an equal number of electron and hole. The Fermi surface consists of two closed hut corrugated Fermi surfaces. The cyclotron masses are moderately heavy, ranging from 1.2 to 7.7m(0). |
