Article Synopsis
- The text presents a concept for a spin-wave diode made of two magnetic layers and a nonmagnetic spacer, demonstrating that the spacer allows both coherent interactions and dissipative coupling.
- The engineered dissipation leads to nonreciprocal behavior, enabling unidirectional wave propagation depending on the sign of the Dzyaloshinskii-Moriya interaction.
- Additionally, the device can function as a spin-wave amplifier when the magnetic layers are powered, and its performance can be improved by adding more layers, linking spin-wave dynamics to non-Hermitian topology.
The plethora of recent discoveries in the field of topological electronic insulators has inspired a search for boson systems with similar properties. There are predictions that ferromagnets on a two-dimensional honeycomb lattice may host chiral edge magnons. In such systems, we theoretically study how magnons and phonons couple.
