Beyond conventional multiferroics: crystal-symmetry-engineered magnetoelectric coupling in multiferroic altermagnets

Ziye Zhu, Xunkai Duan, Igor Žutić, Tong Zhou

This Perspective explores how switchable ferroelectric order can reconfigure crystal symmetry in multiferroic altermagnets to turn spin splitting on and off or reverse its sign, opening new routes to electrically programmable spin functionality and low-power information technologies.
