A magnon is a collective excitation associated with the electrons' spin structure in a crystal lattice. It is a quantum of a spin wave . In materials, a photon quasiparticle is a photon as affected by its interactions with the material.In contrast, magnons in the skyrmion lattice are expected to form emergent Landau levels with a characteristic cyclotron energy Ecycl = ħe |〈 Bem 〉|/ m. Using A UC = 3 a 2 / 2 for the area of the magnetic unit cell with lattice constant a = 4 π / 3 k SkL, this amounts to E cycl / E c2 = 3 / π k SkL / k h 2 ≈ 3 / π.Delta's offering discounted award flights to London, but only for a limited time. Update: Some offers mentioned below are no longer available. View the current offers here. Want to...A corollary is that photons have much longer coherence lengths, while magnons provide a compact platform for quantum 30 effects and manipulation via interactions. The latter point partly allows the unique niche of magnon squeezing to be discussed here. In essence, the two fields are complementary and can gain from each other.The two answers given so far are wrong. A magnon is an excitation carrying spin-$1$. A spinon is an excitation carryong spin-$\frac {1} {2}$. This has nothing to do with it being an excitation above a ferro- or antiferromagnet. The difference is much more dramatic, such that magnons are 'normal'/standard, yet spinons are very special.
