Effect of preferred orientation on GMR and saturation field in Co/Cu multilayers

Abstract We investigated a possible correlation between preferred crystalline orientation and giant magnetoresistance (GMR) and saturation field ( H s ) in Co/Cu multilayers. The results show that the MR ratios and antiferromagnetic (AF) interlayer coupling are closely related to the preferred orientation and are similar for multilayers with 0.9 and 2.1 nm Cu layer thickness, while the preferred orientation dependence of H s changed with different Cu layer thicknesses.
