A Fermi-surface study of palladium disilicide is presented. Experimentally, the Fermi surface and the cyclotron effective masses have been studied using the de Haas–van Alphen (dHvA) effect. Theoretically, the band structure of ${\mathrm{Pd}}_2$Si has been calculated using the linear-muffin-tin-orbital method in the atomic-sphere approximation. The Fermi surface consists of three small hole pockets, an open hole surface, and two large electron sheets. The calculated angular dependence of the extremal cross sections of the Fermi surface is in reasonable agreement with dHvA experiments. Some additional dHvA oscillations are predicted.
