Abstract

The de Haas-van Alphen effect has been used to study the extremal areas, cyclotron masses and spin-splitting nulls on the two Γ-centered sheets of the Fermi surface of iridium for the magnetic field in a (110) plane. The measured extremal areas are in good agreement with recent relativistic- augmented-plane-wave calculations by Andersen. The massenhancement factor determined from a comparison of the calculated and measured masses was found to be 1.31 and rather isotropic for the Γ6 sheet; the enhancement on the Γ5 sheet is distinctly more anisotropic.
