Magnetotransport properties of CoFeB and Co∕Ru interfaces in the current-perpendicular-to-plane geometry
We have investigated magnetotransport properties of CoFeB and Co∕Ru interfaces by measuring the magnetoresistances of sputtered CoFeB-based exchange-biased spin valves and Co∕Ru multilayers on the first antiferromagnetic coupling peak at 4.2K in the current-perpendicular-to-plane geometry. The spin...

| Zusammenfassung: | We have investigated magnetotransport properties of CoFeB and Co∕Ru interfaces by measuring the magnetoresistances of sputtered CoFeB-based exchange-biased spin valves and Co∕Ru multilayers on the first antiferromagnetic coupling peak at 4.2K in the current-perpendicular-to-plane geometry. The spin diffusion length lsf and the spin-scattering asymmetry β of Co40Fe40B20 and Co56Fe24B20 are estimated, and the interface specific resistance 2AR* and the interfacial spin-scattering anisotropy γ of Co∕Ru interfaces are constrained. |
