| contents | Identifying realistic platforms capable of controlled operations with Majorana bound states is a key challenge in the study of topological superconductivity. Among the most promising proposals are magnet-superconductor hybrid devices, which employ magnetic textures to engineer regions of non-trivial topology. Here, we consider the remarkably simple case of $2π$ domain walls in a magnetic ribbon placed on a superconducting substrate. We show that for properly chosen parameters, such domain walls generate topological quasi-one dimensional superconducting wires and give rise to localized Majorana bound states at the ribbon edges. Magnetic $2π$ domain walls are easily created and controlled with existing experimental techniques, thus providing a versatile platform for Majorana manipulations. |
