While electrons are well known to carry both charge and spin, only the electric charge portion is used as an information carrier in modern electronic devices. However, the limits of modern electronics and the impending end of Moore’s Law have rekindled the interest in the development of spintronic devices, which are capable of harnessing the spin of the electrons. It is expected that the widespread adoption of spintronic computing devices can revolutionize information technology similar to the invention of electronics.
