Spin polarization of the conduction bands and secondary electrons of Gd(0001)

PDF Version Also Available for Download.

Description

Angle- and spin-resolved photoemission was utilized to investigate the 5d bulk bands and the surface state of Gd(0001) in the temperature range. of 130 - 350 K The bulk bands at 1-2 eV below the Fermi energy E{sub F} show Stoner-like behavior, while the temperature dependence of the surface state near E{sub F} indicates spin-mixing behavior due to fluctuating local 5d moments. The secondary electron spectra of the Gd surfaces both before and after initial oxygen adsorption show a polarization dip at low kinetic energies due to the extra scattering channel for minority electrons via the unoccupied 4f level.

The secondary electron spectra of the Gd surfaces both before and after initial oxygen adsorption show a polarization dip at low kinetic energies due to the extra scattering channel for minority electrons via the unoccupied 4f level. The temperature dependences of the surface and bulk magnetization are separated using the spin polarization of the surface state and the bulk exchange splitting.
