“…Nontrivial topological magnetic textures are promising elements for potential spintronic 1 , magnonic 2 and logic devices 3 , 4 . Skyrmions have been proposed to be an essential ingredient for achieving such a purpose due to their extraordinary properties related to their topologically nontrivial nature 5 – 7 .…”

In this work, we report the excitation of spin-waves modes in skyrmion clusters hosted in Co/Pt nanodots by applying an in-plane magnetic field pulse. The direction at which the magnetic field is applied enables the excitation of five main spin-waves modes that are understood in terms of only azimuthal-like modes, which are shown to be strongly dependent on the number of skyrmions stabilized in the system. This feature converts the present system in a mechanism to activate and suppress a set of given modes, which in turn we propose to be utilized as a magnonic key based skyrmion cluster. Our results could be useful in manufacturing potential magnonic logic devices based in skyrmionic textures.

“…In the following, we discuss why the special properties of magnonics make it a promising candidate for the hardware-based realization of ANNs -see Magnonic neuromorphic computing: from the general concept of the artificial neural network to its magnonic implementations.

“…One of the main characteristics of oscillator-based RC is that externally injected oscillations can tune mutual couplings or bring noninteracting oscillators into the coupling or synchronization. The geometry of the magnonic oscillatorbased networks may strongly limit the realization of couplings, e.g., magnons propagate only a few hundred nanometers in NiFe [15] resulting in strongest coupling between nearby oscillators [399], [384]. Thus, it is better to use spin-Hall nano oscillators mutually coupled by magnonic low-damping YIGbased waveguides [28], where magnons travel several tens of microns.…”

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.

“…Practical advantages of the magnonics include tunability of the magnon frequencies via the external field, material choice, or the geometry of the magnon media, charge-current-free nature and low power consumption of the spin-wave transfer, and micro-and sub-microscale dimensions of spin waves at microwave frequencies, which allows to target creation of micro-devices for processing of microwave information. Currently, the applied magnonics is progressed towards development of magnon logic devices [7], i.g., waveguides [9], magnon transistors [10], directional couplers [11], majority gates [12,13], non-Boolean devices [5], and neuromorphic circuits [14,15]. Also, magnonics finds its application in spintronic systems [4,[16][17][18][19].…”
