abstract

Proximitizing magnetic textures and $s$-wave superconductors is becoming a platform for engineering topological superconductivity and Majorana fermions by the means of exchange processes. However, the consequences of orbital effects have not yet been fully taken into account. In this work, we investigate the magnetic skyrmion texture-induced orbital effects using a Ginzburg-Landau approach and clarify the conditions under which they can induce superconducting vortices. These orbital effects are then included in Bogoliubov-De-Gennes theory containing the exchange interaction, as well as superconducting vortices (when induced). We find that the topological phase is largely stable to all investigated effects, increasing the realistic promise of skyrmion-superconductor hybrid structures for realization of topological superconductivity.
