Microwave dielectric loss studies on lithium‐zinc ferrites
TLDR
In this article, the authors measured the dielectric parameters of lithium-zinc ferrites with chemical formula Li0.5−x/2Fe2 and showed an increase in dielectrics with temperature.Abstract:
Microwave dielectric parameters are measured for lithium‐zinc ferrites with chemical formula Li0.5−x/2Fe2.5−x/2ZnxO4 (x=0.0, 0.1, 0.3, 0.5, 0.6). All the samples except x=0.5, show an increase in the dielectric loss with temperature. A relaxation‐type mechanism is observed for x=0.5. The results are compared with the low‐frequency dielectric constant and loss.read more
