Tunneling magnetoresistance in altermagnetic RuO${}_2$-based magnetic tunnel junctions

Seunghyeon Noh, Gye-Hyeon Kim, Jiyeon Lee +11

Altermagnets exhibit characteristics akin to antiferromagnets, with spin-split anisotropic bands in momentum space. RuO${}_2$ has been considered as a prototype altermagnet; however,…
