In the race for ever faster, smaller and more energy-efficient devices, scientists around the world have been trying to develop ways to take advantage of the electron’s tiny magnetic movement, known as its spin, in a field of study called spintronics. This requires the engineering of electronic states in solids, which are spin-polarised. For decades
