Spin-wave propagation in metallic CoFe films determined by microfocused frequency-resolved magneto-optic Kerr effect

Lukas Liensberger, Luis Flacke, David Rogerson +3

We investigated the magnetization dynamics of a patterned Co${}_{25}$Fe${}_{75}$-based heterostructure with a novel optical measurement technique that we call microfocused frequency-re…
