摘要：

The spin polarization of photoelectrons from ErFe2 was found to go from near zero to ∼ - 20% upon exposure to 1000 L H2. Exposure to 1000 L O2 yielded zero spin polarization. We conclude that no hydrogen or oxygen induced surface segregation occurs at room temperature in ErFe2 (unlike LaNi5 or FeTi). It is indicated that hydrogen itself causes activation of the ErFe2 surface for hydrogenation. © 1979.
