Exchange coupling between Cr and ferromagnetic thin films
(American Institute of Physics, 2003-05-15)
Exchange bias has been observed in Ni81Fe19/Cr bilayers. The exchange bias field for Cr thickness tCr larger than 62 Å increases with tCr and levels off at tCr=150 Å, whereas coercivity increases without saturation. The ...
Dependence of exchange coupling on antiferromagnetic layer thickness in NiFe/CoO bilayers
(American Institute of Physics, 1998-06-01)
A systematic study of the dependence of exchange coupling in NiFe/CoO bilayers on CoO layer thickness tAF from 5 to 500 Å has been made. For large CoO thicknesses (tAF>100 Å), the exchange field varies as 1/tAF, whereas ...
