Abstract Spin waves in van der Waals magnets hold promise for magnonic devices and circuits down to the two-dimensional limit. However, their short decay lengths pose challenges for practical applications. Here, we report on a material platform consisting of a van der Waals magnet, Fe$_5$GeTe$_2$ (FGT), and a ferrimagnetic insulator of yttrium iron garnet, Y$_3$Fe$_5$O$_{12}$ (YIG), which supports the low-loss propagation of spin waves. Using broadband spin-wave spectroscopy, we observed an increase in spin-wave group velocity with decreasing temperature, which peaks at 30 K in the YIG and FGT/YIG films. This effect is ascribed to a change in the saturation magnetization of YIG and FGT/YIG at low temperature, resulting in a change in the spin-wave dispersion relations. Using micromagnetic simulations, we further investigated spin-wave propagation in an FGT/YIG bilayer and revealed a longer spin-wave decay length in the bilayer than in a single FGT layer, which is due to the lower effective damping in the bilayer. Moreover, asymmetric spin-wave dispersion, induced by a chiral dipolar interaction between the YIG and FGT layers, enables nonreciprocal control of spin-wave propagation.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
