Quantitative investigation of FeMn-based spin-valves by rotating field magnetoresistance measurements
Quantitative investigation of FeMn-based spin-valves by rotating field magnetoresistance measurements
We measure the magnetoresistance of Ta/NiFe/FeMn/NiFe/Co(t(Co))/Cu/Co(t(Co))/NiFe spin-valves as a function of field strength and direction. The exchange bias H-EB and the giant magnetoresistance depend on the Co thickness t(Co), and the resistance shows rotational hysteresis when the external field...

We measure the magnetoresistance of Ta/NiFe/FeMn/NiFe/Co(t(Co))/Cu/Co(t(Co))/NiFe spin-valves as a function of field strength and direction. The exchange bias H-EB and the giant magnetoresistance depend on the Co thickness t(Co), and the resistance shows rotational hysteresis when the external field is close to compensating HEB. A single-domain model reproduces the angular dependence of the magnetoresistance in regions without hysteresis, yields H-EB values in agreement with MOKE, and allows one to precisely determine the interlayer coupling and uniaxial anisotropies although they are much weaker than H-EB.
