Abstract
A switch comprising a spin-transistor and a first control wire. The spin-transistor is configured so that when a magnetic field applied to the spin-transistor is less than a threshold value, the transistor is in a conductive state in which electric current flows through the spin-transistor. When the magnetic field applied to the spin-transistor is greater than the threshold value, the spin-transistor is in a resistive state in which the electric current flowing through the spin-transistor is substantially reduced. The first control wire is for receiving a current to affect the magnetic field applied to the spin-transistor.
