Abstract: Electronic and magnetic properties of nickel as described using experimental spin-split energy band dispersions

Abstract

Angle-resolved photoemission studies of Ni (111) and Ni (100) crystals, used to determine energy-vs-momentum s- and d-band dispersions, show that ferromagnetic nickel can be described by a spin-split itinerant band model with an exchange splitting. An experimental one-electron energy band model for Ni gives a consistent description of various electronic and magnetic properties including Fermi surface radii, spin-polarized field emission and photoemission data, Bohr magneton number and optical properties.
