Abstract
The exchange bias field (H EX ) and the coercivity (H C ) of the intermediate, super-soft magnetic NiFeCuMo layer were investigated for different thicknesses of the bottom NiFe layer. The H EX of the triple-pinned NiFe (4 nm)/NiFeCuMo (t NiFeCuMo = 1 nm)/NiFe (4 nm)/FeMn multilayer has a maximum value of 77 Oe, which is more than that of a single-pinned NiFe (8 nm)/FeMn layer (42 Oe). A multilayer system with the NiFeCuMo layer inserted between the pinned and the free NiFe layers can be used as a giant magnetoresistive spin-valve device for biosensors with improved magnetic sensitivity.
