The article investigates the relationship between altermagnetism and weak ferromagnetism, two distinct but potentially connected magnetic ordering phenomena. Altermagnetism is characterized by spin-split electronic bands without net magnetization, while weak ferromagnetism arises from spin canting due to antisymmetric exchange interactions. The study examines the symmetry conditions and physical mechanisms that link or distinguish these two magnetic states in crystalline materials.
Why it matters
Understanding the interplay between altermagnetism and weak ferromagnetism could advance the design of novel magnetic materials for spintronics applications, where controlling spin without large magnetic fields is a key technological goal.
