Role of magnon-magnon interaction in optical excitation of coherent two-magnon modes

E. A. Arkhipova, A. E. Fedianin, I. A. Eliseyev +4

Two-magnon modes are terahertz-frequency magnetic excitations in antiferromagnets, governed by exchange interactions, involving magnons from the entire Brillouin zone and dominated…
