摘要
压磁开关在文章编号 2400054 中，Hung-Cheng Wu、Taku J. Sato 及其合作者首次观察到铜基化合物在单轴应力作用下弱铁磁成分的有限增强，提供了压磁效应的证据，并证实了通过中子衍射确定的磁空间群。压磁系数有趣的符号变化为通过温度和压力操纵实现可切换磁畴的新功能提供了可能。
Observation of Thermally Induced Piezomagnetic Switching in Cu2OSeO3 Polymorph Synthesized under High-Pressure (Adv. Phys. Res. 11/2024)
Piezomagnetic switching
In article number 2400054, Hung-Cheng Wu, Taku J. Sato, and co-workers report the first observation of a finite enhancement of the weak ferromagnetic component in a Cu-based compound under uniaxial stress, providing evidence of the piezomagnetic effect and confirming the magnetic space group determination resolved by neutron diffraction. An intriguing sign change in the piezomagnetic coefficient holds the potential for realizing new functionality in switchable magnetic domains through temperature and pressure manipulation.
