Unconventional Fermi surface spin textures in the BixPb1−x/Ag(111) surface alloy


Meier, F; Petrov, V; Guerrero, S; Mudry, C; Patthey, L; Osterwalder, J; Dil, J H (2009). Unconventional Fermi surface spin textures in the BixPb1−x/Ag(111) surface alloy. Physical Review. B, Condensed Matter and Materials Physics, 79(24):241408.

Abstract

The Fermi and Rashba energies of surface states in the BixPb1−x/Ag(111) alloy can be tuned simultaneously by changing the composition parameter x. We report on unconventional Fermi surface spin textures observed by spin and angle-resolved photoemission spectroscopy that are correlated with a topological transition of the Fermi surface occurring at x=0.5. We show that the surface states remain fully spin polarized upon alloying and that the spin-polarization vectors are approximately tangential to the constant energy contours. We discuss the implications of the topological transition for the transport of spin.
