Nonmagnetic-magnetic Transitions in Rutile RuO2
Yue-Fei Hou, Siyuan Liu, Wanxiang Fen +4
Rutile RuO has recently attracted great interest, as its magnetic ground state remains controversial. Experimental studies have reported either nonmagnetic (NM) or altermagneti…
Giant Magneto-Optical Effects in Two-Dimensional Flat-Band Antiferromagnets
Ping Yang, Wanxiang Feng, Siyuan Liu +5
In this work, we reveal giant magneto-optical responses in two-dimensional(2D) antiferromagnets with nearly flat electronic bands, based on first-principles calculations and group-…
Altermagnetism: Exploring New Frontiers in Magnetism and Spintronics
Ling Bai, Wanxiang Feng, Siyuan Liu +3
Recent developments have introduced a groundbreaking form of collinear magnetism known as "altermagnetism". This emerging magnetic phase is characterized by robust time-reversal sy…
Observation of surface Fermi arcs in altermagnetic Weyl semimetal CrSb
Wenlong Lu, Shiyu Feng, Yuzhi Wang +10
As a special type of collinear antiferromagnetism (AFM), altermagnetism has garnered significant research interest recently. Altermagnets exhibit broken parity-time symmetry and ze…
