Spin transport across the interface in ferromagnetic/nonmagnetic systems [dataset] Open Access

Understanding interfacial spin transport is key to developing magnetoelectonic devices, however the exact nature of parameters involved is unclear. Here, we report a detailed ferromagnetic reso- nance based spin-transport analysis on a variety of structures of both ferromagnetic (Co, CoFeB) and heavy metal layers (Pt, Ru) in order to fully quantify interfacial spin transport parameters. Enhanced spin-mixing conductance is observed for more closely matched ferromagnet and heavy metal crystal structures, and, significantly, inclusion of a thickness dependent spin diffusion length gives a value of 9.4 ± 0.7 nm for Pt, resolving reported discrepancies.
