High-resolution secondary electron spin-polarisation from gadolinium

Surface magnetic properties of Gd(0 0 0 1) 60 monolayers (ML) thick films grown on W(1 1 0) were studied with spin-resolved photoemission. The spin polarisation of the secondary electrons provides information on electron–hole excitations which produce the majority of low-energy secondary electrons....

description Surface magnetic properties of Gd(0 0 0 1) 60 monolayers (ML) thick films grown on W(1 1 0) were studied with spin-resolved photoemission. The spin polarisation of the secondary electrons provides information on electron–hole excitations which produce the majority of low-energy secondary electrons. In this study, direct and exchange electron–hole scattering of 4f primary electrons indicates that there are contributions to the secondary electrons from both the 4f levels and the valence band.
