However, whether this phenomenon is a unique feature of  or a chemically tunable property of the broader material class has remained unresolved. Here, we demonstrate that type\u2010II multiferroicity in the nickel dihalides is tunable through halide ligand substitution by visualizing the ferroelectric order in monolayer . Using scanning tunneling microscopy (STM), we resolve atomic\u2010scale ferroelectric domains and confirm their magnetoelectric origin through reciprocal manipulation experiments: reorienting magnetic order via electric fields and suppressing the electric polarization with external magnetic fields. Furthermore, we find that the multiferroic state in  is energetically less robust than in its iodide counterpart, consistent with modified superexchange interactions and the reduced spin\u2010orbit coupling (SOC). Our results establish the nickel dihalides as a versatile platform where the stability of magnetoelectric phases can be engineered through chemical\u00a0substitution.<\/jats:p>","DOI":"10.1002\/advs.77081","type":"journal-article","created":{"date-parts":[[2026,8,13]],"date-time":"2026-08-13T15:25:26Z","timestamp":1786634726000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Probing
