Superlong‐Range Magnetic Coupling and Ferromagnetic Spin Freezing in Mechanoluminescent Semiconductor Eu:SrAl 2 O 4 (Adv. Sci. 38/2025)
Year: 2025
Type: article
Abstract: Ferromagnetism New ferromagnetism is realized by superlong-range coupling via magnetic polarons for sparse magnetic spins of Eu2+ in mechanoluminescent SrAl2O4. 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.
