Abstract
In this paper, we present direct evidence for induced spin on Ge at the Fe/Ge interface in an Fe/amorphous Ge multilayer. X-ray magnetic circular dichroism at the Ge L edge accesses the spin polarization of 4sp and 3d unoccupied density of states both showing antiparallel alignment to the adjacent Fe.
