Abstract (Englisch)

The aim of this project is the development of new magnetic materials and prototype devices for high temperature applications i.e. up to 450C working temperature. New standards and measurement protocols will also be developed and defined for high temperature permanent magnets. The discovery of high -performance NdFeB magnets in 1983 has led to an extraordinary development of permanent magnet applications. The annual global production of these materials is presently over 10000 tonnes. The properties of these materials however rapidly degrade as temperature is increased and they cannot be used above 150°C-180°C. From these temperatures and up to 300°C, the Sm (Co, Cu, Fe, Zr) magnets are preferred to the NdFeb. Above this temperature, no material is available although important potential applications exist in the fields of aeronautics, the space (satellite) industry, electronics, and the automotive (petrol and electric) industry.
