About spin electronics

In addition to the charge of the electrons, spin electronics also uses their so-called spin. This electron spin is a quantum mechanical property and can be understood in simplified terms as the rotation of the electrons around their own axis. This is linked to a magnetic moment that leads to the formation of "atomic bar magnets" (atomic spins) in magnetic materials. They are suitable for processing and storing information. Through targeted electrical manipulation, it would be possible to create faster, more energy-saving and more powerful components for information technology.
