However, its implementation has typically been limited by material-specific polarization requirements or by the need for auxiliary exchange coupling and compositional tuning. Here, we demonstrate that deterministic control of AOS can instead be achieved purely through optical engineering. By tailoring the polarization distribution and focusing of the excitation light, we shift the selectivity from intrinsic material properties to external optical beam shaping.

Our results establish optical beam design as a universal control knob for magnetization dynamics in ferromagnetic systems, defining a scalable pathway for integrating ultrafast spintronic functionality with on-chip photonics.\n                  <\/jats:p>","DOI":"10.1038\/s41467-026-77572-3","type":"journal-article","created":{"date-parts":[[2026,9,15]],"date-time":"2026-09-15T16:33:40Z","timestamp":1789490020000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Optical beam shaping induced reconfigurable magnetic domains"],"prefix":"10.1038","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-9672-5494","authenticated-orcid":false,"given":"Muhammad Waleed","family":"Khalid","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheena K.
