Studies of deposition order anomaly of exchange coupling in bilayers and trilayers of NiFe and CoO
(American Institute of Physics, 1997-04-15)
The temperature dependence of the exchange field and coercivity and the effect of deposition order have been studied in a series of bilayer (NiFe/CoO and CoO/NiFe) and trilayer (NiFe/CoO/NiFe) films. A profound difference ...
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 ...
