Abstract

Oxygen adsorption on the close-packed surfaces of trivalent heavy lanthanide metals leads to the formation of well-ordered surface-oxide systems. These systems are characterized by fully occupied oxygen-induced surface states, resembling the surface states of the clean metal surfaces. For the magnetic lanthanides, these states exhibit temperature-dependent magnetic splittings with constant finite values above the respective highest magnetic ordering temperatures, (formula presented) Angle-resolved photoemission from Gd to Ho reveals a systematic behavior of the splittings: the magnitudes are proportional to the (formula presented) moment and their temperature dependencies scale with (formula presented).
