摘要

We report on the investigation of spin-wave propagation in a micro-structured Co_2Mn_(0.6)Fe_(0.4) (CMFS) Heusler waveguide. The reduced magnetic losses of this compound compared to the commonly used Ni_(81)Fe_(19) allow for the observation of spin-wave propagation over distances as high as 75 μm via Brillouin light scattering (BLS) microscopy. In the linear regime, a maximum decay length of 16.7 μm of the spin-wave amplitude was found. The coherence length of the observed spin-wave modes was estimated to be at least 16 μm via phase-resolved BLS techniques.
