Research Trends and Future Research Directions of Permanent Magnetic Materials
Permanent magnetic materials are essential for converting mechanical and electric energy,and are needed in electric vehicles,electronics,wind turbines,and etc.However,high performance rare-earth element based magnets have many limitations,including critical materials problems and the degradation of magnetic properties at elevated temperatures.There has been increasing international demand to solve these problems,and to develop new magnets with reduced rare earth materials,or free magnets based on metallic alloys.This paper describes current research trends,and state of art and future research directions for next generation permanent magnetic materials,to accelerate their research and rapid industrialization.
