Surface Acoustic Wave Manipulation of Magnetic Skyrmions for Tunable Nanoscale Oscillators (Adv. Phys. Res. 8/2025)
A Skyrmion Nano-oscillator Operated by Acoustic Waves
This study introduces a skyrmion-based oscillator driven by surface acoustic waves (SAWs) through magnetoelastic coupling. Precise tunability of the oscillator's frequency through varying the strain amplitude induced by a SAW and device dimensions is demonstrated in micromagnetic simulations. The cover image illustrates a skyrmion-based oscillator under the action of a surface acoustic wave. In Research Article 2400206, Jinxing Zhang, Tianxiang Nan and co-workers demonstrate how the proposed design offers a promising pathway for advancing nanoscale microwave frequency converters and spread spectrum modulation technologies.
