Two-dimensional Dual-Switchable Ferroelectric Altermagnets: Altering Electrons and Magnons
ShuaiYu Wang, Wei-Wei Wang, Jiaxuan Fan +3
Ferroelectric altermagnets (FEAMs) offer unique magnetoelectric coupling properties by combining the characteristics of both antiferromagnets and ferromagnets, yet their multifunct…
