Novel ferromagnetic ring structures for device applications


The research and development of Magnetic Random Access Memory (MRAM) and magnetic logic devices is of keen interest to the computer industry. The development of computers with high density, fast access times, non-volatility and low power consumption will u ndoubtedly affect many different sectors of society including business and media, aeronautics and space technology, security and the defense industry. Computers have become an integral part of our everyday lives and we are becoming increasingly reliant on them to storeimportant information. Recent advances in materials processing technology and nanotechnology have opened up new lines of research involving spin electronics. This project proposes the investigation of novel ferromagnetic nanopatterned ring str uctures, which display a fascinating range of magnetisation states and can be probed using magnetoresistance. These mesoscopic structures can be engineered to display different stable magnetised states depending on their shape, dimensions, and composition. An understanding of the stability of different states, and the ability to control the switching field, enables nanomagnets to find application in patterned media, in whicheach uniaxial element stores one bit of data, high-density magnetic random access me mory (MRAMs), magnetic logic and other magnetoelectronic devices, such as spin-filters and spin-transistors. The successful development of this design will have a significant impact on the European computer and electronics industries, as well as advancing our current understanding of magnetic and electrical materials on the micron and nanoscale. This project contributes to several European priority areas including: information society technologies, nanotechnology, nanoelectronics, new production processes a nd devices.European laboratories have an outstanding strength in basic science and technology. Europe is in a good position to take the current research in magnetic and electrical materials and develop#
