This study investigates altermagnetic magnon splitting in rare-earth orthoferrites (RFeO3), examining the phenomenon from both non-relativistic and relativistic theoretical perspectives. The researchers predict how magnons — quantized spin waves in magnetic materials — exhibit energy splitting characteristic of altermagnetism, a recently identified magnetic phase distinct from ferromagnetism and antiferromagnetism. The work also explores how this splitting can be tuned by varying the rare-earth element (R), offering a pathway to control magnonic properties in this material family.
Why it matters
Altermagnetic materials are of significant interest for next-generation spintronic devices, as they combine the absence of net magnetization (useful for stability) with spin-split electronic and magnonic bands (useful for spin transport). Understanding and tuning magnon splitting in RFeO3 could inform the design of low-dissipation magnonic components for data processing and communication technologies.
