Bulk band structure of Ru O2 measured with soft x-ray angle-resolved photoemission spectroscopy
Altermagnetism exhibits unique physical properties such as spin-momentum locking, anomalous Hall effect, nontrivial topological phase, and giant magnetoresistance. Among all the predicted candidates, several room-temperature altermagnets are suggested to host significant potential applications. RuO2 has been proposed as the most promising candidate. However, recently, there is intense debate about
