Spin diffusion lengths
WebNov 22, 2024 · The spin diffusion length for platinum (Pt) has been reported in the literature in a wide range of 0.5–14 nm, and in particular it is a constant value independent of Pt's thickness. Here, the key reasonings behind such a wide range of reported values of spin diffusion length have been identified comprehensively. http://helper.ipam.ucla.edu/publications/le2009/le2009_7881.pdf
