Summary on Grant Application Form
The microelectronic revolution is based on the use of the charge of the electron to store and manipulate information. Spintronics aims to do this taking advantage of the magnetic degree of freedom of the electron, its spin. Basic sensor devices operating on this principle form the read-head of today's high-density disk drives, and recent popular articles in e.g. Science, New Scientist, IEEE Spectrum, and Physics Today discuss the promise of this new technology. As a result of recent SRIF2 investment and new collaborative opportunities, Leeds will shortly have access to world-class nanofabrication facilities that will allow us to undertake an exciting new range of experiments in this area. The Leeds Nanomanufacturing Institute has provided us with the funds to appoint a PhD student to work in this area, and we have a commitment from the Hitachi Cambridge Laboratory that the student will have access to their state-of-the-art electron beam lithography facilities. We are requesting a contribution from EPSRC towards travel, consumable, and minor equipment costs in the project. Our focus in this project is on the spintronic effects of domain walls in magnetic nanocircuits, and we will carry out a series of realted experiments in this area. In particular, we will study current-induced domain wall motion and attempt to prove the principle that with careful engineering of materials, device geoemtry and the time-structure of the exciting current pulses we can reduce the required current density, and hence power, required to move a magnetic domain wall and hence store information.
