Abstract :
Microwave properties of Fe-based nanocrystalline alloy particles mainly depend on the crystal structure and particle morphology. It’s difficult to build up their relationship directly, so magnetic properties are introduced as intermediaries. In this paper, nanocrystalline Fe73.5Cu1Nb3Si13.5B7alloy powders were prepared and tested by the structural, magnetic and microwave measurement. It’s found that besides particle size, the structural properties such as grain size or lattice constant have important influence on the sample’s static magnetic properties, and such influence effectively extends to its complex permeability. Moreover, the exchange coupling and surface-effect were discussed in this issue.
