We have studied the effects of interlayer exchange coupling in the Co/Cu multilayer films by varying the thickness of the Cu spacer layer in the range 0≤tCu≤15nm for fixed Co thickness. We observed marked changes in both the magnetic and magnetotransport properties for varied tCu due to the effect of interlayer exchange coupling. For tCu=5nm, a complex magnetic spin state develops in the PHE output which may be attributed to anti-ferromagnetic coupling between the adjacent magnetic layers in contrast with ferromagnetic coupling observed for tCu=2nm. We have also made a direct comparison of AMR and PHE voltages as a function of the orientation of the constant applied field relative to the current direction. We observed that PHE output voltage is extremely sensitive to exact spin orientation when compared with AMR voltage measured simultaneously on the same device. When the applied field is less than the switching field of the device PHE voltage reveals a departure from the sin2θ behaviour predicted by theory due to domain wall propagation. © 2004 Elsevier B.V.||Source Title:||Sensors and Actuators, A: Physical||URI:||http://scholarbank.nus.edu.sg/handle/10635/82916||ISSN:||09244247||DOI:||10.1016/j.sna.2004.03.042|
