Abstract
A systematic study of the dependence of exchange coupling in NiFe/CoO bilayers on CoO layer thickness from 5 to 500 Å has been made. For large CoO thicknesses the exchange field varies as whereas for small CoO thicknesses finite-size scaling of the Néel temperature and also the blocking temperature dominate.
