We are all familiar with the image of electrons zipping around an atom's nucleus and forming chemical bonds in molecules and materials. But what is less known is that electrons have an additional unique property: spin. It is difficult to make an analogy, but one could crudely describe electron spin as a spinning-top rotating around its axis. But what is even more interesting is that when spins of electrons align together in a material this leads to the well-known phenomenon of magnetism.
