Spintronics aims to develop electronic devices whose resistance is controlled by the spin of the charge carriers that flow through them. This approach is illustrated by the operation of the most basic spintronic device, the spin valve, which can be formed if two ferromagnetic electrodes are separated by a thin tunnelling barrier.
