Low energy spin-polarized (e,2e) coincidence spectroscopy of Fe layer on W(110)

Full text: Spin-polarized (e,2e) spectroscopy was applied to study ferromagnetic layers of iron deposited on nonmagnetic substrate. Normal incidence and 26 eV primary electrons were used to record energy-and momentum distributions of correlated electron pairs. Polarization of incident beam was chosen to be perpendicular to the scattering plane. Experimental results confirm, that the Fe film changes the easy magnetization axis when the film thickness reaches the critical value of about 50 ML. Spin-dependent total energy distribution and spin-dependent parallel-to-the-surface momentum distribution reflect mostly spin-dependent distributions of electronic states in energy-momentum space.
