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…
Enhanced magneto-optical intensity effect in a helicity-preserving all-dielectric metasurface at Mie resonances and the anapole state
P. V. Zorina, D. O. Ignatyeva, A. E. Bezmenova +4
Nanophotonic structures provide an efficient route to enhancing magneto-optical effects by concentrating electromagnetic fields at subwavelength scales. In this work, we propose an…
The prospects of nonthermal magnetization switching in near-compensated rare earth iron garnets
N. I. Gribova, D. O. Ignatyeva, N. A. Gusev +2
Ultrafast spin dynamics in a magnetically compensated rare earth iron garnet film driven by femtosecond optical pulses through the inverse Faraday effect is theoretically investiga…
Exceptionally high Verdet constant in gold nanodisc arrays
Gajendra Mulay, Shraddha Choudhary, Ashwin A Tulapurkar +4
Magneto-optical effects in non-magnetic noble metals can be greatly enhanced by leveraging the in-plane Lorentz force at engineered plasmonic resonances. We demonstrate a 2D array…
Unusual sign-changing Faraday effect in nanometer-thick magnetic films
A. V. Belkova, D. O. Ignatyeva, A. N. Kalish +3
It is generally believed that the magneto-optical Faraday effect appears in the the bulk of a magnetic material and its sign is fully determined by the sign of the non-diagonal per…
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…
