Magnonics: a new research area in spintronics and spin wave electronics

TLDR

The paper aims to explore physical processes associated with spin‑wave propagation in complex nano‑ and micro‑dimensional magnetic structures. It employs measurement techniques and theoretical approaches to study these processes. Recent findings demonstrate that magnonic structures enable spin‑wave propagation in distributed periodic, lumped, coupled waveguide, and controllable configurations, supporting signal processing and transmission systems and suggesting promising circuitry designs for future development.

Abstract

Recent results in magnonics – a topical and rapidly developing branch of spintronics and magnetoelectronics – are presented. The paper describes measurement techniques and theoretical approaches used to explore physical processes associated with the spin-wave propagation in complex nano- and micro-dimensional magnetic structures. The results of the application of magnetic structures in signal processing and transmission systems are discussed. In particular, results on spin wave propagation in distributed magnetic periodic structures, lumped systems, coupled waveguide structures, and controllable magnonic structures are considered. Specific examples of circuitry based on magnonic structures are discussed, and possibilities for further developing this circuitry are explored.
