Spintronics gets a magnetic flute
Progress in understanding the microscopic behaviour of electrons continues to open up new frontiers for materials and device research, and vice versa. Watching how electrons move, at high current density, through structures that are less than 100 nm in size has revealed a wealth of new physics based on the 'spin' properties of these particles, and potentially a new class of electronic device: a spin-transfer switch for magnetic-memory 'spintronics'.
