Schematic for optimized structures used in ab initio calculations of (a) Pt/Co and (b) Pt/Co/O, where Pt, Co and O are represented by blue, green and red balls, respectively. Calculated band structures for (c) Pt (4 ML)/Co (4 ML) and (d) Pt (4 ML)/Co (4 ML)/O (1 ML) with SOC, the red and blue symbols indicate two opposite spin directions of the electrons. (e) Zoom-in of the band dispersion in (d) for calculation of Rashba parameter. (f) Schematic of charge transfer from Co to O.
