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

机械发光半导体Eu:SrAl2O4的超长距离磁耦合和铁磁自旋冻结（ei）

铁磁性在机械发光的SrAl2O4中，Eu2+的稀疏磁自旋通过磁极化子的超远程耦合实现了新的铁磁性。这种材料在手指接触时会发光，激活极化子来控制磁性。在力-光-电子-自旋多重控制和能量转换方面，有望有前所未有的应用。
