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.
