Surface ferrimagnetic order in RuO2 film
Jiahua Lu, Huangzhaoxiang Chen, Zhe Zhang +11
RuO2, widely proposed as a prototypical altermagnet, remains intensely debated with regard to its magnetic nature. Here, we demonstrate that RuO2 is non-magnetic in the bulk, but p…

A Route to Nonrelativistic Altermagnetic Spin Splitting via Ultrafast Light
Huang-Zhao-Xiang Chen, Lin-Ding Yuan, Wen-Hao Liu +3
We identify a nonequilibrium route for generating altermagnetic spin splitting in antiferromagnet by ultrafast light. Unlike existing strategies, this route does not require relati…
