Spin-Wave Dynamics in Ultra-thin Ferromagnetic Films, Patterned, and Non-patterned

Exploring spin-waveSpin wave (SW) dynamics opens new avenues for technological applications across various fields. This chapter provides a comprehensive review of spin-waveSpin wave (SW) dynamics in both patterned and non-patterned ferromagnetic thin films, and emphasizes the significance of perpendicular magnetic anisotropyPerpendicular magnetic anisotropy (PMA) in this context as well. The chapter begins with an overview of the basic concept and relevance of spin wavesSpin wave (SW), followed by a detailed discussion of Brillouin light scatteringBrillouin light scattering (BLS) methodology. We explore the unique properties of spin wavesSpin wave (SW) in patterned films, such as magnonic crystalsMagnonic crystals (MC), and a comparative study with the behaviour in continuous films has been presented in detail. The future perspective from technological point of view of spin-wave research is vast, ranging from high-frequency data transmission to quantum information processing. Here we highlighted applications encompass spin-wave logic devices, magnonic waveguide, quantum computingSpin wave computing, and the role of spin wavesSpin wave (SW) in the development of novel materials with tailored magnetic properties. Finally, this review addresses the challenges associated with achieving precise control over spin-waveSpin wave (SW) propagation, elucidating spin-waveSpin wave (SW) interactions at the nanoscale, and integrating spin-waveSpin wave (SW) technology with existing technological frameworks.
