Spin-Polarized Electron Energy Loss Spectroscopy on Fe(100) Thin Films Grown on Ag(100)
Abstract
We report sharp spin-dependent energy loss features in electron scattering from bcc Fe(100) thin films grown on Ag(100). Majority spin features are observed at ~1.8 and 2.5 eV energy loss, and a minority spin feature is observed at ~2.0 eV energy loss. The majority spin peaks are attributed to spin-flip exchange scattering from the Fe films. The minority spin peak is attributed to non-flip exchange scattering with an energy corresponding to the separation between occupied and unoccupied minority spin bands. The observed peak energies compare favourably with electronic structure calculations for Fe and with spin-resolved photoemission and inverse photoemission results.
