Research output: Contribution to journalArticlepeer-review


Co-substituted Ni-Zn ferrite was prepared by a chemical codeposition. The electromagnetic properties, zero reflection conditions and simulated reflection losses of the samples were investigated. As a result, it is found that with Co contents rising, the saturation magnetization (MS) shows a tendency of decrease, while coercivity (Hc) varies clearly. In addition, Ni-Zn ferrite with different cobalt content can meet zero reflection conditions. And the reflection loss calculation indicates that with the increase of cobalt contents, the reflection loss peak moves to high frequency; moreover, to increase Co content more than 0.15, and the absorption intensity as well as the absorbing band of microwave absorber are enhanced obviously.
