Nonlinear Magnon Magnetic Moment Transport in Triangular-Lattice f-Wave Antialtermagnets
The study investigates spin excitations (magnons) in frustrated triangular-lattice antiferromagnets, which form an odd-parity f-wave magnet called an antialtermagnet. It shows these magnons carry a magnetic moment perpendicular to the ordered plane. Furthermore, nonlinear thermal transport effects like the spin-splitter and Edelstein effects provide clear experimental signatures of these f-wave magnons.
