Nature Communications, Published online: 30 April 2026; doi:10.1038/s41467-026-71938-3 Previous studies of vortex Majorana zero modes (MZMs) in iron-based superconductors have predominantly considered the case where magnetic field is parallel to the Dirac axis. Here, the authors focus on vortices oriented perpendicular to the Dirac axis, finding that such vortices are more favorable for observing vortex MZMs.
