abstract = {Electrodeposited Co-Cu/Cu multilayers were prepared under a
variety of deposition conditions on either a polycrystalline
Ti foil or on a silicon wafer covered by a Ta buffer and a
Cu seed layer. X-ray diffraction (XRD)revealed a strong
(111)texture for all multilayers with clear satellite peaks
for the multilayers on Si/Ta/Cu substrates, in some cases
for up to three reflections. Cross-sectional transmission
electron microscopy investigations indicated a much more
uniform multilayer structure on the Si/Ta/Cu substrates. The
bilayer periods from XRD satellite reflections were in
reasonable agreement with nominal values. An analysis of the
overall chemical composition of the multilayers gave
estimates of the sublayer thickness changes due to the
Co-dissolution process during the Cu deposition pulse. The
XRD lattice spacing data indicated a behaviour close to a
simple "multilayer" Vegard's law which was, however, further
refined by taking into account elastic strains as well. In
agreement with the structural studies, magnetoresistance
data also indicated the formation of more perfect
multilayers on the smooth Si/Ta/Cu substrates. An analysis
of the magnetoresistance behaviour revealed the presence of
superparamagnetic (SPM)regions in the magnetic layers. The
contribution of these SPM regions to the total observed
giant magnetoresistance was found to be dominating under
certain deposition conditions, e.g., for magnetic layer
thicknesses less than 1 nm (about 5 monolayers).},
