Engineering 2D high-temperature ferromagnets with large in-plane anisotropy via alkali-metal decoration in a tetragonal CoSe monolayer
Yiran Peng, Yanfeng Ge, Yong Liu +1
Two-dimensional (2D) ferromagnetic materials with high Curie temperature () and large magnetic anisotropy energy (MAE) are critical for nanoscale spintronics but remain…

Single Pair of Charge-two Weyl Fermions in Chiral Boron Allotropes
Hui-Jing Zheng, Yan Gao, Yanfeng Ge +2
The realization of a minimal Weyl semimetal (WSM) hosting a single pair of Weyl points (WPs) has thus far been restricted to magnetic systems, since time-reversal symmetry generall…

Symmetry-Protected Minimum of Four Conventional Weyl Points in Nonmagnetic Crystals
Ze-Xin Xue, Ke-Xin Pang, Yun-Yun Bai +3
Realizing nonmagnetic Weyl semimetals (WSMs) with the minimal number of conventional Weyl points (WPs) and a clean Fermi surface remains a central challenge. Here, combining symmet…
