Degeneracy and trajectory control of spin eigenmodes excited by fs-optical pulses in a nearly compensated ferrimagnet
G. Yu. Levkin, D. M. Krichevsky, N. A. Gusev +4
We investigate optically excited spin dynamics in a uniaxial ferrimagnet near the magnetization compensation point under a magnetic field applied along the magnetic anisotropy axis…

Magnon-photon coupling in the YIG-based disk and ring microcavities
S. S. Demirchyan, D. M. Krichevsky, V. I. Belotelov
Optomagnonic dielectric resonators offer a promising platform for the bidirectional conversion of microwave and optical photons at the single quantum level. Current implementation…

All-dielectric Metaphotonics for Advanced THz Control of Spins
Lucas van Gerven, Daria O. Ignatyeva, Daniil V. Konkov +7
While nearly single cycle THz pulse is conventionally accepted as the stimulus for the fastest and the most energy efficient control of spins in magnets, all-dielectric metasurface…
