Altermagnetic Multiferroics: Symmetry-Locked Magnetoelectric Coupling
arXiv:2507.07553 · doi:10.1038/s41563-026-02518-5
Abstract
Multiferroics exhibit significant potential for low-power spintronic devices due to magnetoelectric coupling. Here, we discuss an emerging class of altermagnetic multiferroics, a system demonstrating distinct advantages including zero net magnetization (eliminating stray fields), momentum-dependent spin splitting (enabling electric-field control of spin currents), and intrinsic strong magnetoelectric coupling originating from spin-space symmetry.
