Ultrafast controlling net magnetization in g-wave altermagnets via laser fields
Zhaobo Zhou, Sangeeta Sharma, Junjie He
The diverse nodal spin structures in d/g/i-wave altermagnets (AM) may cause distinct light-induced spin responses yet remain poorly understood. Using time-dependent density functio…

Accelerated ultrafast demagnetization of an interlayer-exchange-coupled Co/Mn/Co trilayer
Jendrik Gördes, Ivar Kumberg, Chowdhury S. Awsaf +7
We investigate the ultrafast magnetization dynamics of an interlayer-exchange-coupled Co/Mn/Co trilayer system after excitation with an ultrafast optical pump. We probe element- an…
