The interplay between strong spin-orbit coupling (SOC) and magnetization at interfaces has been a pathway for the observation of novel physical phenomena, quasi-particles and potential for design new devices. The interfaces formed by ferromagnetic materials (FM) materials and with strong SOC are strongly improved by proximity effects which allow the introduction of unexpected electronic properties in the system. It is possible to list many examples like the presence of Skyrmions on the surface of FM transition metal/heavy metals multilayers and the observation of spin-orbit torque in topological insulator and ferromagnetic metal interface. In this work, we use multilayers of Bismuth and Cobalt, as SOC and FM materials, respectively, in orde...
