Emergent Interfacial Magnetism in Epitaxial RuO
Yudi Yang, Zhuang Qian, Shi Liu +1
The magnetic ground state of the altermagnet candidate RuO remains controversial, with magnetic signatures observed mainly in epitaxial films. Here we show, using first-princip…

Electrical Regulation of Transverse Spin Currents in Unconventional Magnetic Ferroeletrics
Yudi Yang, Zhuang Qian, Ruichun Xiao +4
We identify hexagonal YMnO as a material realization of the elusive -phase of unconventional magnetism, a noncollinear, noncoplanar antiferromagnetic state defined by intri…
