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. More details can be found in the Research Article by Xu-Guang Zheng, Chao-Nan Xu, and co-workers (DOI: 10.1002/advs.202509474).
