Unexpected oscillation states in magnetic vortices could enable coupling across different physical systems

Key Points:
- Researchers at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) discovered previously unobserved Floquet states in tiny magnetic vortices using low-energy magnetic wave excitation instead of energy-intensive laser pulses.
- These Floquet states arise from rhythmic modulation caused by a subtle circular motion of the vortex core, producing a frequency comb of resonance lines rather than a single resonance peak.
- The process requires only microwatt-level energy input, making it highly efficient compared to traditional methods that rely on strong laser pulses.
- This discovery could enable a universal adapter to bridge electronics, spintronics, and quantum devices by synchronizing disparate systems across different frequency ranges.
- The findings open new research avenues in fundamental magnetism and have potential applications in neuromorphic
