Defect-Charge-Driven 90° Switching in HfO2
Muting Xie, Hongyu Yu, Zhihao Dai +3
Hafnium dioxide (HfO2) is a CMOS-compatible ferroelectric showing both 180° and 90° switching, yet the microscopic nature of the 90° pathway remains unresolved. We show that the 90…
Moiré-Induced Magnetoelectricity in Twisted Bilayer NiI2
Haiyan Zhu, Hongyu Yu, Weiqin Zhu +3
Twisted magnetic van der Waals (vdW) materials offer a promising route for multiferroic engineering, yet modeling large-scale moiré superlattices remains challenging. Leveraging a…
Deterministic and Efficient Switching of Sliding Ferroelectrics
Shihan Deng, Hongyu Yu, Junyi Ji +2
Recent studies highlight the scientific importance and broad application prospects of two-dimensional (2D) sliding ferroelectrics, which prevalently exhibit vertical polarization w…
Symmetry Strategy for Rapid Discovery of Abundant Fractional Quantum Ferroelectrics
Guoliang Yu, Junyi Ji, Changsong Xu +1
Traditional ferroelectrics are limited by Neumann's principle, which confines exploration of ferroelectrics within polar point groups. Our recent work [Nat. Commun. 15, 135, (2024)…
Evaluating Gilbert Damping in Magnetic Insulators from First Principles
Liangliang Hong, Changsong Xu, Hongjun Xiang
Magnetic damping has a significant impact on the performance of various magnetic and spintronic devices, making it a long-standing focus of research. The strength of magnetic dampi…
Triple-Well Charge Density Wave Transition Driven by Cooperation between Peierls-like Effect and Antiferromagnetic Order in FeGe
Binhua Zhang, Junyi Ji, Changsong Xu +1
Kagome materials provide a promising platform to explore intriguing correlated phenomena including magnetism, charge density wave (CDW), and nontrivial band topology. Recently, a C…
General time-reversal equivariant neural network potential for magnetic materials
Hongyu Yu, Boyu Liu, Yang Zhong +5
This study introduces time-reversal E(3)-equivariant neural network and SpinGNN++ framework for constructing a comprehensive interatomic potential for magnetic systems, encompassin…
