Nanotechnology allows us to modify the properties of materials in a new way, creating functionality that is not possible in larger-scale versions of the same material. In this lecture I show how nanometre-scale magnetic materials can be used to build a new generation of microelectronic devices that use both the spin and the charge of the electron. Applications for such devices range from the battlefield through to MP3 players. I conclude the lecture by describing how this research unexpectedly ended up in the formation of a spin-out company which is now selling anti-counterfeiting solutions to brand owners around the world.
