In condensed matter physics, a spin wave is a propagating disturbance in the ordering of a magnetic material. These low-lying collective excitations occur in magnetic lattices with …

If we flip a single spin, the energy is. But it is possible to create an excitation with much less energy than this! What we can do is let the spins “share” the spin flip, which is a key feature of …

Spin Waves: Theory and Applications serves not only as an introduction to an active area of research, but also as a reference for workers in the field.

Jan 27, 2025 · Spin waves, or magnons, are essential for next-generation energy-efficient spintronics and magnonics. Yet, visualizing spin-wave dynamics at nanoscale and microwave …

Apr 9, 2024 · Here, we image the three-dimensional dynamics of spin waves excited in a synthetic antiferromagnet, with nanoscale spatial resolution and sub-ns temporal resolution, using time …

Nov 28, 2021 · Spin waves are the dynamic eigen-excitations of a magnetic system. They provide the basis for the description of spatial and temporal evolution of the magnetization distribution …

We study the cases of a ferromagnet and of an antiferromagnet. We also discuss the use of neutron techniques in measuring the dispersion of spin waves. Developed in the 50's, the spin …

Mar 9, 2020 · Spin Wave Theory. To describe the behavior of magnons and phonons collectively, scientists developed the spin wave theory. With this, phonons and magnons should have …

Aug 1, 2020 · Spin waves are quantum objects and several phenomena involving them require that they are treated as such. In this chapter, we present a quantum approach of spin waves …

Jun 23, 2020 · After an introduction to magnetic interactions and spin-wave physics, all relevant basic aspects of spin-wave computing and individual spin-wave devices are reviewed. The …
