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 1990s, researchers started to reveal the unique characteristics of the photon/phonon/magnon spectra with band gaps in the artificial periodic structures of corresponding media, which are called photonic/phononic/magnonic crystals, respectively 52,109,110 . Since then, MCs are of great interest in both pure wave physics and application oriented magnonics [58][59][60]69,70 . Fig.…”

“…In recent years, a new subfield of magnonics called topological magnonics is developing rapidly. Research in this field is focused on the novel characteristics of topological nontrivial magnon modes 58,60,64,125,177,178 . In the view of theory, topological magnonics can provide a new access to help people understanding the topological nontrivial phenomena of magnonic systems in condensed matter, such as Dirac magnons, Weyl magnons and higher-order topological magnons 92,[179][180][181][182][183][184][185] .…”

Engineered quantum systems enabling novel capabilities for communication, computation, and sensing have blossomed in the last decade. Architectures benefiting from combining distinct and complementary physical quantum systems have emerged as promising platforms for developing quantum technologies. A new class of hybrid quantum systems based on collective spin excitations in ferromagnetic materials has led to the diverse set of experimental platforms which are outlined in this review article. The coherent interaction between microwave cavity modes and collective spin-wave modes is presented as the backbone of the development of more complex hybrid quantum systems. Indeed, quanta of excitation of the spin-wave modes, called magnons, can also interact coherently with optical photons, phonons, and superconducting qubits in the fields of cavity optomagnonics, cavity magnomechanics, and quantum magnonics, respectively. Notably, quantum magnonics provides a promising platform for performing quantum optics experiments in magnetically-ordered solid-state systems. Applications of hybrid quantum systems based on magnonics for quantum information processing and quantum sensing are also outlined briefly.

“…Most recently, spin wave driven skyrmion motion draws a lot of attention due to some advantages such as low dissipation and producing less heat [20][21][22]. In ferromagnets, the spin wave is only right-circularly polarized and drives the skyrmion motion towards the spin wave source in the presence of a Hall motion related to its topological charge, which can be understood from the momentum conservation [23].…”

An investigation of spin waves interacting with antiferromagnetic spin textures is meaningful for future spintronic and magnonic-based memory and logic applications. In this work, we numerically study the skyrmion dynamics driven by circularly polarized spin waves in antiferromagnets and propose a method of suppressing the Hall motion. It is demonstrated that the application of two circularly polarized spin waves with opposite chirality allows the skyrmion motion straightly along the intersection line of the two spin wave sources. The skyrmion speed depending on these parameters of the spin waves and system is estimated, and a comparison with other methods is provided. Furthermore, two depinning behaviors of the skyrmion related to the strengths of the defect are also observed in the simulations. Thus, the proposed method could be used in precisely modulating the skyrmion dynamics, contributing to skyrmion-based memory device design.
