**7. Summary**

Rare earth magnets play critical role in many advanced technologies. The rapid growth demand for rare earth magnet is placing increased stress on the availability of key rare earth elements. The improvements to manufacturing processes can form near-net-shape product with reduce materials losses and total machining costs. SmFeN magnets can be an alternative to NdFeB magnets for certain applications. SmFeN can be a new generation magnet after the optimisation of the chemical composition of the elements, the preparation of alloy powder, the coercivity mechanism and the preparation of high-performance magnets with enhanced magnetic properties. A lot of research needs to be done for development of new rare-earth magnetic material magnets for high-temperature applications. Additional experiments or analyses can be conducted to further investigate the development of new rare earth magnetic materials for high temperature applications.
