Three-Dimensional Magnonics

Layered, Micro- and Nanostructures

edited by Gianluca Gubbiotti

"Magnonics is a relatively new subfield of modern condensed matter physics, with strong connections to material science and device fabrication in electrical engineering. Just as phonons are the quanta of sound in a solid material, magnons are the quantized excitations of the magnetic field in a solid; the classical counterpart of a magnon is a spin wave. Magnonics aims to harness magnons to transport and process information in a way similar to the way modern electronics uses electrons. Magnonics typically uses designed materials to work towards a goal of useful, mass-produced devices. This volume is a collection of eleven chapters, each written by a different group of experts in the field, all of whom are working to move magnonics from the study of two-dimensional materials, which has dominated the field, to fully three-dimensional structures. The book will be of interest primarily to experimental researchers and graduate students working on magnonics, as well as those working in related areas such as spintronics and nanotechnology. Institutions with broad, active research programs in condensed matter physics or quantum information might also acquire this book as a resource and reference."

Magnonics, a research field that uses spin waves, collective excitations of ordered magnetic materials, or magnons (their quanta) as a tool for signal processing, communication, and computation, has rapidly grown during the past decade because of the low-energy consumption and potential compatibility with next-generation circuits beyond CMOS electronics. The interest in 3D magnonic nanostructures follows the latest trend in conventional electronics based on expansion from 2D planar to 3D vertically integrated structures. To remain on the same technological level, a similar expansion should be realized in magnonics.

Following this trend, this book provides an overview of recent developments in the exploitation of the third dimension in magnonics, with special focus on the propagation of spin waves in layered magnonic crystals, spin textures, curved surfaces, 3D nano-objects, and cavity magnonics. The book is unique in that it addresses, as an alternative to physical patterning, hybrid heterostructures in the form of bilayer systems (metal–insulator, metal-heavy metal, metal–antiferromagnet, and metal–ferroelectric), where new properties of spin waves emerge from interactions between the continuous magnetic film, where spin waves propagate, and the nonmagnetic component, which induces periodic modulation of either the static or the dynamic internal magnetic field of the magnetic film itself. The book comprises 11 chapters written by outstanding international research groups in the field of magnonics and will appeal to anyone involved in magnonics, spintronics, nanotechnology, microwave applications, and nanomagnetism.

 Key Features:

  • This book covers new aspects of the magnonic band structure that appear in the presence of layered nanometric systems.
  • It deals with novel spin wave properties emerging from propagation on curved surfaces.
  • Most books in this area cover the theoretical aspects without discussing specific applications to real samples.
  • No other book discusses hybrid magnonic heterostructures as an alternative to standard nanofabrication techniques for controlling spin wave propagation properties in thin ferromagnetic films.
