14. In Ref. [13] the authors conclude that at high current densities the single layer point contact experiments closely mimic trilayer junctions in which excitations are caused by a spin polarized current and detected via a giant magnetoresistance type of effect. Here the extended film acts as a reference. Hence, excitations lead to a resistance increase and show up as peaks in dV/dI.
15. We assume that strong spin-flip scattering at the Pt/Cu interface effectively forces the spin accumulation at the Pt/Cu interface to zero [16]. For our sample geometry this leads to a smaller spin accumulation at the Cu/Co interface facing the Pt bottom electrode. Under this assumption the polarity dependence of the single layer excitations is consistent with that predicted in Refs. [8,9].

18. The total height of the PD is fixed. Therefore, an increase of the Co layer thickness reduces the asymmetry in spin accumulation and hence could increase the critical currents.
