Scientists Discover Crystal Exhibiting Exotic Spiral Magnetism

August 19, 2021

An exotic form of magnetism has been discovered and linked to an equally exotic type of electrons, according to scientists who analyzed a new crystal in which

Two vertical strings of electrons form magnons. Spin waves passing through the left magnon string are larger than those passing through the right, indicating the difference between an on and off state.
