Fast and slow dynamics at coupled magnetic interfaces: Theory and Experiment. Immediate needs for advances in materials for spin electronics and information technology require a deeper physical understanding of new materials in which interfaces and nanometre dimensions determine properties. Interfacial exchange coupling between magnetic layers is a key issue in the formation of many multilayer structures, and several important issues remain unresolved. This is a proposal for a joint theoretical ....Fast and slow dynamics at coupled magnetic interfaces: Theory and Experiment. Immediate needs for advances in materials for spin electronics and information technology require a deeper physical understanding of new materials in which interfaces and nanometre dimensions determine properties. Interfacial exchange coupling between magnetic layers is a key issue in the formation of many multilayer structures, and several important issues remain unresolved. This is a proposal for a joint theoretical and experimental study of technologically important magnetic interfaces by groups at Universities of Florence, Perugia, Leeds and Western Australia.Read moreRead less
Spin dependent transport in magnetic nanostructures. The ability to use electron spin in electronic circuits has opened new possibilities for designing devices. A well known example is the giant magnetoresistance, a phenomena discovered over fifteen years ago that now plays a key role in current high density magnetic disc drives. Future developments will involve spin dependent transport through structures wherein quantum interference effects will be important. Two basic problems facing the cons ....Spin dependent transport in magnetic nanostructures. The ability to use electron spin in electronic circuits has opened new possibilities for designing devices. A well known example is the giant magnetoresistance, a phenomena discovered over fifteen years ago that now plays a key role in current high density magnetic disc drives. Future developments will involve spin dependent transport through structures wherein quantum interference effects will be important. Two basic problems facing the construction of a complete theory of transport in such ?mesoscopic? conductors will be solved in this project. The results will provide important insights into the dynamics of spin transport through structures such as magnetic nano-wires.Read moreRead less
Investigation of spin excitations in ferromagnetic submicro- and nanostructures. The project will last 12 months and will be devoted to investigation of spin-wave dynamics in thin ferromagnetic-film sub-micro- and nano-structures for possible applications to microwave\millimetre wave electronic devices and to novel magnetic memory devices. Excitation of spin-wave modes in confined in magnetic nano- and submicro-objects (from the super-paramagnetic size limit up to 700 nm) will be theoreticall ....Investigation of spin excitations in ferromagnetic submicro- and nanostructures. The project will last 12 months and will be devoted to investigation of spin-wave dynamics in thin ferromagnetic-film sub-micro- and nano-structures for possible applications to microwave\millimetre wave electronic devices and to novel magnetic memory devices. Excitation of spin-wave modes in confined in magnetic nano- and submicro-objects (from the super-paramagnetic size limit up to 700 nm) will be theoretically studied. In co-operation with other research groups the obtained theoretical results will be experimentally verified. New information on microwave properties of the structures will be obtained. Possibility of application of the magnetic structures to construct new microwave devices will be considered.Read moreRead less
Materials World Network for the Study of Macromolecular Ferrofluids. This work will develop an understanding that will allow us to optimise the properties of ferrofluids (magnetic liquids) to suit particular applications. Although the primary application that will be investigated is the treatment of retinal detachment, the results will be applicable to a wide range of applications including ferrofluid-based actuators, electromagnetic micropumps and fluid based valves and sealing systems.

Although the primary application that will be investigated is the treatment of retinal detachment, the results will be applicable to a wide range of applications including ferrofluid-based actuators, electromagnetic micropumps and fluid based valves and sealing systems. During the course of this work, young Australian scientists will be trained in a cross-disciplinary environment in a variety of aspects of both nano- and bio- technology that are a key part of the National Research Priority: Frontier Technologies for Building and Transforming Australian Industries.Read moreRead less
