Abstract

Spin waves are collective precessional oscillations of electron spins that propagate through ordered magnetic media. Their quantised excitations are magnons, bosonic quasiparticles that carry angular momentum and energy. Magnonics explores magnon dynamics for both practical applications—such as information processing, signal routing, and sensing—and for advancing fundamental physics in various platforms. It is an emergent, fast-growing area of solid-state physics that bridges condensed-matter physics, materials science, microwave engineering, and quantum technologies. This mini-colloquium will gather leading research groups in magnonics from Vienna, Linz, and Graz with invited guests from abroad to present recent results and outline current challenges. We will highlight progress in radio-frequency (RF) applied magnonics, AI-driven inverse-design magnonics, where machine-learning tools optimise complex magnonic circuits, and will cover quantum magnonics, focusing on the single-magnon regime. The colloquium aims to catalyse dialogue across subfields, foster collaborations, and map opportunities for magnon-based technologies in computing, communications, and precision sensing.
