a Dependence of ξMI and ξMD on PML thickness in Series A (filled symbol) and B (open symbol) samples. Solid curve shows the fitting results using theoretical formula. b, c Schematic of two generation mechanisms of σMD. Yellow arrow indicates magnetization of FM (m) and red arrow is spin orientation of spin current. b Spin–orbit precession effect triggered by spin–orbit field (blue arrow) at the interface (σSOP). c Proposed spin-Hall precession effect within FM (σSHP).
