Spin polarization of secondary electrons from Fe(110) excited by unpolarized primary electrons

Spin polarization, structure and chemical composition of the Rh/Fe(100) interface

“…The remanent magnetization was generated by several constant current (dc) pulses through the coil. For the SPLEED measurements the Fe crystal is biased to À10 V with respect to ground [20] in order to reduce effects of strayfields on trajectories on low energy electrons.…”

Monte Carlo study of the spin polarization enhancement in the low‐energy secondary electron emission from ferromagnetic materials

“…Because this hump vanished after the surface exposure to oxygen in the experiment, 22 it is related to the surface structure. 6 Because the surface structure is not considered in our simulation model, the simulation result shows the narrower peak. The large hump at ¾12 eV in the experimental result is not understood at present.…”

Magnetic Domain Imaging with Spin-Polarized SEM

“…The possibility of magnetic domain observation using this phenomenon was proposed by DiStefano in 1978 [23], without knowing the experimental results of Chrobok et al The relationships among the polarization, primary energy, and secondary electron energy, however, are not so simple, since the secondary electrons suffer spin-dependent inelastic scattering during the process of emission [24][25][26]. Figure 1 shows the secondary electron energy dependency of secondary intensity and polarization for an Fe (110) sample, for primary energies from 50 to 2,000 eV [27]. As is well known, the secondary intensity decreases exponentially with the secondary energy.…”
