Tunable Hyperbolic Media: Magnon-Polaritons in Canted Antiferromagnets

Unusual reflection and propagation properties of electromagnetic waves in magnetic media have been in the spotlight for many decades. Much attention h…

Stress-Induced Spin Currents In Antiferromagnets Offer New Spintronic Potential.

Applying mechanical stress to insulating antiferromagnetic materials, such as FeOOH, Cr2O3 and NaMnX, generates symmetry-protected pure spin currents via the piezospintronic effect, offering a potentially robust and compatible pathway for low-dissipation spintronic devices, and a novel first-principles method allows for the investigation of related spin dipole phenomena like ferrotoroidicity.
