摘 要：The spin transport was investigated in permally（Py）/Mg O/Ag junction with lateral spin valve structure.Non-local lateral spin valves measurement was carried out to determine the spin accumulation signal in Ag strip, and the spin diffusion length in Ag of the lateral spin valves was extracted from devices with the different distances between injector and detector. The experimental results are found that spin accumulation and spin diffusion length（λs） could be significantly enhanced in Ag strip with Mg O capping layer, and those effects may be attributed to the low-surface spin scattering rate in Ag with an Mg O capping layer.
