The use of magnetic fields is an external stimulus for the control of material properties, which is of considerable technical interest, since magnetic fields can easily be generated and controlled. Magnetically controlled materials such as suspensions of magnetic nano- and microparticles - ferrofluids and magneto-rheological fluids - have the ability to exhibit strong changes of material behaviour at reasonable technical effort. In materials formed by a particulate magnetic component in a complex matrix, the mutual influence of particles and matrix provides an additional set of parameters in the material behaviour. This can provide the possibility for a magnetically controlled change of material properties. The knowledge of the interaction between the particles and the surrounding matrix is an important element for the understanding of the material behaviour itself, and thus the basis for a targeted development of such materials for novel applications in actuators and sensors. In the centre, the Priority Programme focusses on five key issues: It must be clarified, how (1) the material behaviour of a magnetically controllable hybrid material is influenced by the particle-matrix interaction and how appropriate materials can be synthesised. A multi-scale modelling of the material properties is (2) the fundament for the understanding of the behaviour of the materials necessary to explain their magnetic controllability at a microscopic level. The modelling is also needed for the establishment of constitutive material laws, which are needed for the design of applications. Closely connected to this modelling of the material properties is (3) the experimental evaluation of the material properties and its connection to changes in the microstructure. Based on this understanding of the magnetic hybrid materials one can answer the question (4) what kind of possibilities they offer in novel actoric and sensory applications, as well as the question (5) how the effectiveness of the biomedical use of magnetic nanoparticles can be improved by a control of the interaction between the functionalised particles and tissue.
