Surface Functionalization Enables Two-Dimensional Altermagnetism and Giant Tunnel Magnetoresistance
Zhou Cui, Ziye Zhu, Bowen Hao +7
Two-dimensional (2D) altermagnets (AMs) are highly desirable for ultrafast, stray-field-free spintronics because they combine compensated magnetic order and momentum-dependent spin…
Altermagnets Enable Gate-Switchable Helical and Chiral Topological Transport with Spin-Valley-Momentum-Locked Dual Protection
Xianzhang Chen, Jiayong Zhang, Bowen Hao +5
We establish a unified, symmetry-driven framework that combines the alternating spin splitting of altermagnets with valley topology to realize and electrically interconvert helical…
Interface-Enhanced Superconductivity in Ultrathin TiN Proximitized by Topological Insulators
Renjie Xie, Bowen Hao, Min Ge +11
High-quality topological insulator-superconductor (TI-SC) heterostructure with an atomically sharp and well-controlled interface is crucial for realizing topological superconductiv…
Symmetry-Driven Unconventional Magnetoelectric Coupling in Perovskite Altermagnets: From Bulk to the Two-Dimensional Limit
Zhou Cui, Ziye Zhu, Xunkai Duan +4
The emergence of altermagnets establishes a new paradigm for multiferroics. Unlike conventional multiferroics relying on direct magnetoelectric coupling, multiferroic altermagnets…
Emergent Multiferroic Altermagnets and Spin Control via Noncollinear Molecular Polarization
Ziye Zhu, Yuntian Liu, Xunkai Duan +5
Altermagnets, with spin splitting and vanishing magnetization, have been attributed to many fascinating phenomena and potential applications. In particular, integrating ferroelectr…
Two-Dimensional Ferroelectric Altermagnets: From Model to Material Realization
Ziye Zhu, Xunkai Duan, Jiayong Zhang +3
Multiferroic altermagnets offer new opportunities for magnetoelectric coupling and electrically tunable spintronics. However, due to intrinsic symmetry conflicts between altermagne…
