SUMMARY:Nanotechnology: Challenging chips and crime - Russell Cowburn\, TF

DESCRIPTION:Nanotechnology allows us to modify the properties of materials
  in a new way\, creating functionality that is not possible in larger-scal
 e versions of the same material. This is particularly the case for magneti
 c materials\, where the very simple linear magnetic properties that might 
 exist in the bulk can be tailored and made much more complex once structur
 es approach 100nm in size or less. In this lecture I show how nanometre-sc
 ale magnetic materials can be used to build a new generation of microelect
 ronic devices that use both the spin and the charge of the electron. Appli
 cations for such devices range from the battlefield through to MP3 players
 . I conclude the lecture by describing how this research unexpectedly ende
 d up in the formation of a spin-out company which is now selling anti-coun
 terfeiting solutions to brand owners around the world.
