| 1 | Investigation of influence of micro-structure on magnetic properties of amorphous powder core显示文摘The influence of micro-structure on magnetic properties of amorphous powder core was investigated. The results show that the amorphous powders of the powder core become crystallized with the increase of annealing temperature, and the permeability decreases from 60 to 12, the core loss increases from 0.2 to 0.3 W·cm-3, DC-bias characteristic was improved with further increase of annealing temperature, and the magnetic properties become deteriorated due to decrease of permeability and enhancement of coercive force resulting from the crystallization of amorphous powder. | GUO Feng BA Shan LI Deren LU Zhichao LU Caowei WANG Jun | 2006 | Rare Metals2006，25，z1： | 2 |
