Microwave resonances of magnetic skyrmions in thin film multilayers:
Writing in Nature Communications, our group has published the first study of the dynamical properties of Néel skyrmions in thin film heterostructures at microwave frequencies. As well as discovering a new collective skyrmion oscillation, we also demonstrated how the skyrmion resonant mode frequencies can be modulated via the magnetic multilayer architecture. These abilities promise a bright future for skyrmions in magnonic and synaptic devices.
We gratefully acknowledge our collaborators in Germany, Ukraine and China.
