Abstract

We report on the investigation of spin-wave propagation in a micro-structured Co 2Mn 0.6Fe 0.4Si (CMFS) Heusler waveguide. The reduced magnetic losses of this compound compared to the commonly used Ni 81Fe 19 allow for the observation of spin-wave propagation over distances as high as 75 m via Brillouin light scattering (BLS) microscopy. In the linear regime, a maximum decay length of 16.7 m of the spin-wave amplitude was found. The coherence length of the observed spin-wave modes was estimated to be at least 16 m via phase-resolved BLS techniques.
