摘要
We experimentally realized rolled-up permalloy stripes to form three-dimensional ring-like ferromagnetic structures. By means of microwave absorption spectroscopy, we find multiple resonances occurring above a demagnetization field threshold which depends on the ring%26apos;s axial width. Our experimental data can be well modeled by assuming both axial and azimuthal spin-wave confinement.
