Spin Splitting Coupled Visible‐Light Driven Injection Photocurrent in Bilayer Altermagnets
ABSTRACT Altermagnets host symmetry‐protected spin splitting without net magnetization, offering a new platform for spin‐dependent transport and optical responses. Here we demonstrate that bilayer altermagnets enable efficient and tunable second‐order injection photocurrents in the visible regime via interlayer couplin...
