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…
Revisiting Ferroelectricity Beyond Polar Space Groups
Yudi Yang, Changming Ke, Shi Liu
Ferroelectricity, a hallmark of spontaneous inversion-symmetry breaking, has been a central concept in condensed matter physics and functional materials research, yet recent discov…
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…
Topological Control of Transition Metal Networks for Reversible High-Capacity Li-rich Cathodes
Changming Ke, Yudi Yang, Minjun Wang +2
Developing high-energy-density batteries is essential for advancing sustainable energy technologies. However, leading cathode materials such as Li-rich oxides, including LiMnO$…
