抄録
Ceramic composites were fabricated from powder mixtures of BaTiO3 and Ni0:3Zn0:7FexO4 with different Fe contents of x ¼ 1:8, 1.9, 2.0, 2.1, and 2.2 to examine the effect of Fe content on the dielectric permittivity ("r) of the composite samples (these are referred to as Fe1.8, Fe1.9, Fe2.0, Fe2.1, and Fe2.2 composites or samples, respectively). The "r values of the composites were greatly affected by the Fe content such that a small "r value of the Fe1.8 composite sample steeply increased with increasing Fe content by about three orders of magnitude for the Fe2.1 and Fe2.2 samples. The strong Fe content dependence could be correlated with the incorporation of Ti4þ ions into the octahedral sublattices in the ferrite structure. Therefore, the markedly increasing "r values for the Fe2.1 and Fe2.2 composite samples can be attributed to the presence of Fe2þ ions synergetically created by the Ti-substitution and Fe-rich composition.
