Strain-Induced Antiferromagnetic-to-Altermagnetic Phase Transition and Topology in $({\mathrm{CrO}}_2{)}_1/({\mathrm{TaO}}_2{)}_2$ Superlattice

Wanfei Shan, Qun Yang, Prineha Narang

Topological aspects in altermagnets have come into focus recently, and tuning the antiferromagnetic (AFM) state into an altermagnetic phase remains an active frontier. We realize b…
