Spintronics is a relatively new field of electronics that exploits the spin of the electron to create new devices and increase the efficiency of existing ones. The spin is a quantum mechanical property of the electron that can be thought of as its angular momentum. By harnessing the spin of the electron, spintronics devices can be faster, more energy efficient, and more data dense than traditional electronics.
Some of the emerging trends in spintronics include the development of spin-based devices and circuits, the use of spintronics for data storage and processing, and the use of spintronics for energy conversion and storage.
