“…Propagation dynamics of magnon-phonon polarons may enable the encoding to networks of magnonic computing elements, such as a magnetic parametron. A magnetic parametron is the nonlinear magnetic oscillator characterized by magnetization precession phases discretized into 0 or π [474]. The function of parametron is demonstrated by a YIG/Pt thin disk under parallel parametric pumping.…”

“…The bistability of the "magnon parametron", a parametrically driven magnetic disk, can be used as an Ising spin memory and stochastic "p-bit" for probabilistic computations [474]. The entanglement principle sketched above for resonantly excited magnets works as well for the magnon parametron [521] at even lesser drive powers.…”

Magnonics addresses the physical properties of spin waves and utilizes them for data processing. Scalability down to atomic dimensions, operation in the GHz-to-THz frequency range, utilization of nonlinear and nonreciprocal phenomena, and compatibility with CMOS are just a few of many advantages offered by magnons. Although magnonics is still primarily positioned in the academic domain, the scientific and technological challenges of the field are being extensively investigated, and many proof-of-concept prototypes have already been realized in laboratories. This roadmap is a product of the collective work of many authors that covers versatile spin-wave computing approaches, conceptual building blocks, and underlying physical phenomena. In particular, the roadmap discusses the computation operations with Boolean digital data, unconventional approaches like neuromorphic computing, and the progress towards magnon-based quantum computing. The article is organized as a collection of sub-sections grouped into seven large thematic sections. Each sub-section is prepared by one or a group of authors and concludes with a brief description of current challenges and the outlook of further development for each research direction.

“…Recent research in magnon-photon interactions focuses on the magnon polariton hybrids of the Kittel magnon and a microwave cavity mode [17][18][19][20]. Purely magnetic systems strongly coupled to cavity photons can operate as gradient memories [21], probabilistic-bits [22], or to distill the entanglement of interacting magnons [23]. It also realizes (quantum) information transfer between a localized spin system and a distant superconducting qubit [24].…”

We experimentally and theoretically demonstrate that nonlinear spin-wave interactions suppress the hybrid magnon-photon quasiparticle or "magnon polariton" in microwave spectra of an yttrium iron garnet film detected by an on-chip split-ring resonator. We observe a strong coupling between the Kittel magnon and microwave cavity mode in terms of an anti-crossing as a function of magnetic fields at low microwave input powers, but a complete closing of the anti-crossing gap at high powers. The experimental results are well explained by a theoretical model including the three-magnon decay of the Kittel magnon into spin waves. The gap closure originates from the saturation of the ferromagnetic resonance above the Suhl instability threshold by a coherent back reaction from the spin waves.

A general expression for the magnetostatic field generated by mechanical deformations to a ferromagnetic material in the continuum description is derived. Linearization with respect to the displacement vector is shown to be well defined. To demonstrate the use of the formulation, two examples are discussed. First, a complete derivation of the magneto‐rotation coupling for a uniformly magnetized film is given. Second, the lowest asymmetric mode of Lamb waves propagating through a magnetic vortex is shown to induce an in‐plane magnetostatic field localized around the vortex core.
