Conduction-electron g factor on the X-pocket holes in iridium.

Abstract

The conduction-electron Zeeman splitting on the ${\mathit{X}}_{3}$- and ${\mathit{X}}_{4}$-pocket holes in iridium has been measured by the de Haas--van Alphen technique. A large anisotropy in the cyclotron orbit g factor (${\mathit{g}}_{\mathit{c}}$) is found on both pockets. Calculations of the ${\mathit{g}}_{\mathit{c}}$ factor by a relativistic linear muffin-tin orbital method including an external magnetic field are also presented. The obtained results are compared with previous results on the X-pocket holes in palladium and platinum.
