| 10 | Electronic devices have traditionally been based on controlling the flow of charge. However, electrons carry both charge and “spin”, the latter being responsible for magnetic phenomena. | |||
| 11 | Over the last decade or so, the fields of Spintronics and magnetism have evolved into one large field. This is primarily due to two key experimentally demonstrated phenomena: spin injection into metals/semiconductors from magnetic contacts and spin induced magnetization dynamics of magnets by spin transfer torque. | |||
| 12 | ||||
| 13 | These demonstrations suggest an all-spin approach to information processing. Magnets inject spins and spins turn magnets forming a closed “'''''ecosystem'''''” without the need to convert to charge. A recently proposed concept called '''''all spin logic''''' (ASL) uses magnets to represent non-volatile data and communicate between them using spin currents with the energy coming from the power supply. | |||
| 14 | ||||
| 15 | ASL approach to information processing uses a formalism recently developed at Purdue University for integrated spin-magnet circuits. This approach is particularly powerful in that it combines various spin related phenomena such as spin-injection, spin-transport and spin-detection with that of magnet dynamics into one unified '''''spin-circuit''''' theory. This formalism does not use approximations in defining the elements of the spin-magnet circuit as usually done in defining compact models. At the same time, it is capable of modeling integrated circuits composed of many magnets interconnected with spin-coherent interconnects. | |||
