TL;DR: Linewidth measurements reveal that the lifetime of the magnons is asymmetric with respect to their counter-propagating directions, and the lifetime asymmetry is dependent on the magnon frequency, being more pronounced, the higher the frequency.

TL;DR: In this article, the experimental observation of band gaps in a synthetic nanostructured magnonic crystal composed of two different magnetic materials was reported, in the form of a one-dimensional periodic array comprising alternating Permalloy and cobalt nanostripes.

TL;DR: Using advanced electron beam lithographic techniques, a series of novel bicomponent magnonic crystals which exhibit well-defined frequency bandgaps are fabricated, and it is observed that the bandgap width decreases with increasing permalloy stripe width, but increases with increasing cobalt stripe width.

TL;DR: In this paper, strong interfacial Dzyaloshinskii-Moriya interactions have been observed in an ultrathin Pt/CoFeB film, and the observed high asymmetry of the monotonic spin wave dispersion relation is attributed to strong DZM interactions present at the Pt/coFeB interface, which should enhance the significance of CoFeB as an important material for magnonic and spintronic applications.
