The Science of Existence (44-10-5) Magnons


A magnon is a collective excitation that quantizes the spin wave which characterizes the spin property of all quanta. Magnons emerge from waves of flipping spin. They explain electron behavior in a crystal lattice. Swiss physicist Felix Bloch introduced magnons in 1930 to elucidate abrupt, spontaneous changes in magnetism at low temperatures; whence their name.
