Spin wave - Wikipedia
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 continuous symmetry.
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 a spin wave excitation

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 of a magnetic object under the general assumption that locally the length of …
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 waves theory is one of the milestones in magnetism and continues to …
Phonons, Magnons, and Their Applications to Spin Wave Theory
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 harmonic frequencies that dampen out over time, becoming harmonic.
Quantum Theory of Spin Waves: Magnons | SpringerLink
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 based on the Holstein–Primakoff transformation from the spin operators into magnon operators.
