Title: Evidence for polarized boron in Co-B and Fe-B alloys

Abstract

By exploiting the tunability of synchrotron radiation in measurements of spin-resolved photoemission it has proved possible to obtain information on the polarization of the valence electrons of Co-B and Fe-B amorphous magnetic alloys. Both the spin-integrated and spin-resolved energy distribution curves show a marked dependence on photon energy indicating that the p states of boron hybridize with the d states of the transition metals giving rise to mixed states in the binding energy range 1 to 5 eV. The observed polarization and spin-resolved densities of states imply that in the above restricted energy range there is a net negative polarization of the boron states.
