| 内容記述 | The carbonyl-iron powder (CIP) was annealed in the air for the composite core of high Q-factor RF-inductor to see if an oxidized film would be formed on CIP surface. Results showed that not only the surface-oxidized film thickness but also the crystallite diameter and coecivity increased when increasing the annealing temperature and time. The most suitable annealing conditions were found to be 240oC and 6 h: about 40 nm of Fe3O4 and Fe2O3 were formed on the CIP surface under these conditions. A magnetic composite with the surface-oxidized film on magnetic particles was fabricated and its permeability measured. The inductance and resistance were calculated by a 3D full-model electromagnetic analyzer on the basis of measured permeability and the Q-factor was then estimated using these characteristics. The highest Q-factor, 33, was observed at 1.8 GHz, which was higher than that of the air-core from 0.1 to 1.8 GHz. | |||||||||||
