Fermi surface and band structure of ferromagnetic nickel

Abstract

The band structure and Fermi surface of ferromagnetic nickel obtained by Hodges, Gold, and Stone is reexamined in the light of recent data of Stark on the large Γ-centered Fermi surface sp↑ and sp↓ sheets. The energy band structure, calculated by Hodges, Gold, and Stone using an interpolation scheme, fails to give good agreement with Stark's data. We present here results of a calculation on the basis of a modified interpolation scheme and we get good agreement with the experimental results on the large Γ-centered sheets as well as on the smaller Fermi-surface sheets. We report our calculations for extremal areas and band masses of various orbits, magneton number, and the density of states.
