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 frequenc; 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.展开更多

As-deposited LLTO thin films showed amorphous-like phases and when deposition temperature increases the ionic conductivity raises accordingly. The ionic conductivity of LLTO thin film reaches 8.7×10 -6 S/cm when the deposition temperature is 400℃, which shows that the LLTO thin films deposited by magnetron sputtering are suitable for application as an electrolyte for thin film microbattery.展开更多
