In this study, we experimentally investigated the interfacial Dzyaloshisnkii-Moriaya interaction (DMI) and the spin-Hall angle (SHA) of magnetic Co/Gd/Pt multilayers with respect to the repetition number N of the multilayers. The DMI and SHA are important variables that govern the stability and mobility of a homochiral spin structure, respectively. The experimental results show that the ratio between the DMI and the dipole energy from the domain wall gradually decreases as N increases, which is expected to be hard to achieve homochiral spin structure for larger N and the values of SHA remain constant irrespective of N. The observed SHA invariance indicates that the Pt layers in repetition have a negligible effect on the SHA.
