Superconductor-magnet hybrid structures provide a platform for investigating topological phases with localized Majorana states. Such states have previously been predicted in the presence of elongated Skyrmions in the magnetic layer. Here, we consider 2π domain walls that can be easily controlled experimentally. We show that Majorana states can occur in these systems and discuss the possibility of building Majorana chains using a sequence of 2π domain walls.
