Altermagnetism from coincident Van Hove singularities: application to $\hat{I}º$-Cl

Yue Yu, Han-Gyeol Suh, Mercè Roig +1

Realizing two-dimensional (2D) altermagnets is important for spintronics applications. Here we propose a microscopic template for stabilizing 2D altermagnetism through Van Hove sin…
