Magnetic multilayer films are of great scientific interest and technological importance. Here we propose novel and innovative studies on such films subject to different growth and processing conditions. Our principal aim is to relate their magnetic properties to the detailed nature of their physical nanostructure and, in particular, to determine how both are affected by ion irradiation. To achieve it we shall use a focused ion beam machine, for property modification, and a combination of nanoanalytical electron microscopy and transmission Lorentz microscopy to characterise the physical and magnetic properties with very high spatial resolution. Emphasis will be given to the detailed nature of the interfaces and how these change under ion irradiation. The ion beam machine will be used to produce structures with dimensions as small as a few 10's of nanometres. Substantial property change can be expected as the dimensions of the structures fall increasingly below one micron. Multilayer films to be patterned include spin-tunnel junctions, spin-valves, exchange-biased layers and films with perpendicular anisotropy. TEM experiments will be performed at temperatures varying from room temperature to 250C to cover the range important for diverse applications, particularly those associated with sensing and storage.
