The environmental and energy problem more and more get the attention of the countries all over the world, energy conservation and emission reduction has become the focus of attention of the common humanity. Magnetic materials in the national economy is an important base materials, in recent years, appeared by electric drives and electronic control device of products of drive, automatic control and function of trend, the key is one of the core materials soft magnetic materials. Soft magnetic materials in various devices play energy transfer and conversion function coupling. Improve the efficiency and reduce the soft magnetic ferrite core material loss in energy saving and environmental pollution control has the great significance. This paper briefly introduces the current research status of soft magnetic materials and the progress in research of high performance magnetic materials such as the amorphous, nanocrystalline and soft magnetic composite by author in recent years.
