Spintronics

Spintronics [136-138] is a word used to describe transport in a mesoscopic junction in which the transport medium (or the electrodes) contain unpaired electron spins. There are different aspects of spintronics, but the simplest idea is that one can transport spin without necessarily transporting charge. This leads to the idea of a molecular spin transistor, and other spin phenomena such as spin valves and spin gates. 

One difficulty with the spintronics area using molecules [139-141] has been that, like simple transport, it will change with the geometry of the interface. Nevertheless, spintronic applications are intriguing, and this has become a new focus area for molecular electronics. 

One such quantum property of the electron is its spin, i.e., its magnetism. Devices that rely on an electron s spin to perform their functions form the foundation of spintronics (short for spin-based electronics), also defined as magneto-electronics. Information-processing teclmology has thus far relied on purely charge-based devices, ranging from the now outdated vacuum tube to today s million-transistor microchips. The conventional electronic

The spin-orbit interaction is also called spin-orbit effect or spin-orbit coupling, which is one cause of magnetocrystalline anisotropy. SOC, the intrinsic interaction between a particle spin and its motion, is responsible for various important phenomena, ranging from atomic fine structure to topological condensed matter physics. SOC plays a major role in many important condensed matter phenomena and applications, including spin and anomalous Hall effects, topological insulators, spintronics, spin quantum computation, and so on.
