Unraveling the magnetic order in iron chalcogenides and pnictides at atomic scale is pivotal for understanding their unconventional superconducting pairing mechanism, but is experimentally challenging. Here, by utilizing spin‐polarized scanning tunneling microscopy, real‐space spin contrasts are suc...
