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…

Magnetophotonic waveguide nanostructure for selective ultrafast optical excitation of high-K spin dynamics
Savelii V. Lutsenko, Anastasia E. Khramova, Daria O. Ignatyeva +7
Optomagnonics provides a promising method of a Joule-loss-free spin control that can be performed at ultrafast timescale. However, the cornerstone of optomagnonics is impossibility…

Spatially inhomogeneous inverse Faraday effect provides tunable nonthermal excitation of exchange dominated spin waves
Denis M. Krichevsky, Vladislav A. Ozerov, Alexandra V. Belkova +11
We demonstrate optical nonthermal excitation of exchange dominated spin waves of different orders in a magnetophotonic crystal. The magnetophotonic structure consists of a thin mag…
