Lifted Kramers spin degeneracy (LKSD) has been among the central topics of condensed-matter physics since the dawn of the band theory of solids1,2. It underpins established practical applications as well as current frontier research, ranging from mag... Read More about Altermagnetic lifting of Kramers spin degeneracy.

Observation of time-reversal symmetry breaking in the band structure of altermagnetic RuO 2 (2024)
Journal Article
Fedchenko, O., Minár, J., Akashdeep, A., D’Souza, S. W., Vasilyev, D., Tkach, O., …Elmers, H. (2024). Observation of time-reversal symmetry breaking in the band structure of altermagnetic RuO 2. Science Advances, 10(5), Article eadj4883. https://doi.org/10.1126/sciadv.adj4883

Altermagnets are an emerging elementary class of collinear magnets. Unlike ferromagnets, their distinct crystal symmetries inhibit magnetization while, unlike antiferromagnets, they promote strong spin polarization in the band structure. The correspo...
