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…

Spin and lattice dynamics at the spin-reorientation transitions in the rare-earth orthoferrite Sm $_{0.55}$ Tb $_{0.45}$ FeO $_{3}$

R. M. Dubrovin, A. I. Brulev, N. R. Vovk +10

Linear and non-linear couplings of magnetic and lattice excitations are at the heart of many fascinating magnetophononic phenomena observed in rare-earth orthoferrites, the distinc…
