WebOct 18, 2024 · The common belief is that excitations of magnets are always deconfined ``bulk'' spin waves spread out in space, whose quanta are called magnons. In reality all materials have surfaces and interfaces that break translation symmetry, giving rise to excitations that are confined to them, in addition to the deconfined ones. The conditions … WebThe elementary particle of a spin-wave is called a Magnon. Like a Photon a Magnon carries the energy where f is the precession frequency of the individual spins in a spin wave. They carry a spin equal to one. Magnons can be imagined as one complete precession distributed over a chain of spins.
