| Abstract: | High-permeability nanocrystalline particle is one of the most important approaches to develop the new generation of electromagnetic wave absorbing materials.Based on the exchange coupling,finite-size and surface effect of nanostructure,the static magnetic characterizations and dynamic magnetization mechanism of high-permeability nanocrystalline particles are introduced in this paper.The experimental results are discussed in combination with the recent research development in this field promoted by the local and abroad researchers. Finally,the problems in present work and developing trends of future research were submitted. |
