SPIN EFFECTS IN EMPTY ELECTRONIC STATES OF NI(001)

Abstract

In this paper spin-dependent calculations within the one-step model of inverse photoemission are presented for the Ni(001) surface. They are compared with spin-resolved inverse photoemission and target current spectroscopy data and are used to construct an effective surface barrier potential. The measured exchange splitting of the X1 point about 9 eV above the Fermi level as well as dispersions E(k(parallel-to)) and splittings of bulk and surface states are shown to be well described by the calculations.
