Superlong‐Range Magnetic Coupling and Ferromagnetic Spin Freezing in Mechanoluminescent Semiconductor Eu:SrAl <sub>2</sub> O <sub>4</sub> (Adv. Sci. 38/2025)

FerromagnetismNew ferromagnetism is realized by superlong-range coupling via magnetic polarons for sparse magnetic spins of Eu 2+ in mechanoluminescent SrAl 2 O 4 .The material emits light upon finger contact, activating polarons to control magnetism.Unprecedented applications are expected in force-light-electron-spin multiple control and energy conversion.
