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…

Spontaneous and impulsive stimulated Raman scattering from two-magnon modes in a cubic antiferromagnet
Anatolii E. Fedianin, Alexandra M. Kalashnikova, Johan H. Mentink
Exchange interactions govern the ordering between microscopic spins and the highest-frequency spin excitations - magnons at the edge of the Brillouin zone. As well known from spont…

Coherent THz Spin Dynamics in Antiferromagnets Beyond the Approximation of the Néel vector
F. Formisano, T. T. Gareev, D. I. Khusyainov +8
Controlled generation of coherent spin waves with highest possible frequencies and the shortest possible wavelengths is a cornerstone of spintronics and magnonics. Here, using the…
