Aspects of spin polarised transport

Spin electronics is the emerging discipline which seeks to exploit the spin of the electron in the pursuit of new areas of physics and of novel devices and applications. It can be broadly defined as the technology which differentially manipulates the two families of electronic carriers, the up and down spins. The technical basis for Spin Electronics resides in the transport properties of metallic ferromagnets which are central to the discipline and are used as sources and analysers of spin-polarised currents. We have developed a totally new model for domain wall resistance in the framework of the two spin channel model which invokes spin mixing which derives from the deviation of spin direction from the local magnetisation direction in passage through the wallSIGLEAvailable from British Library Document Supply Centre-DSC:D213757 / BLDSC - British Library Document Supply CentreGBUnited Kingdo
