Title:
Change in Interface Magnetism of an Exchange-Coupled System Due to the Presence of Nonmagnetic Spacers 
Abstract:
We report on the effect of nonmagnetic spacer layers on the interface magnetism and the exchange bias in the archetypical [Co/CoO]16 system. The separation of the magnetic bilayers by Au layers with various thicknesses dAu$\geq$25 nm leads to a threefold increase of the exchange bias field (Heb). Reflectometry with polarized neutrons does not reveal any appreciable change in the domain population. This result is in agreement with the observation that the granular microstructure within the [Co/Co...    »
