1Magnon — There is a place named Magnon in Gabon. A magnon is a collective excitation of the electrons spin structure in a crystal lattice. In contrast, a phonon is a collective excitation of the crystal lattice atoms or ions. In the equivalent wave… …
2magnon — ▪ physics small quantity of energy corresponding to a specific decrease in magnetic (magnet) strength that travels as a unit through a magnetic substance. In a magnetic substance, such as iron, each atom acts as a small individual… …
3Spin wave — Spin waves are propagating disturbances in the ordering of magnetic materials. These low lying collective excitations occur in magnetic lattices with continuous symmetry. From the equivalent quasiparticle point of view, spin waves are known as… …
