Optically excited spin dynamics of thermally metastable skyrmions in Fe${}_{0.75}$Co${}_{0.25}$Si

Jantje Kalin, Sibylle Sievers, Heiko Füser +5

We investigate the microwave spin excitations of the cubic chiral magnet Fe${}_{0.75}$Co${}_{0.25}$Si as driven by the thermal modulation of magnetic interactions via laser heating and…
