Four samples of Zn1-xLi0.5xFe2+0.5xO4 (x = 0.25, 0.5, 0.75, and 1) were
prepared by the ceramic method. AC electrical conductivity and the dielectric
constant were determined. High abnormal value of the dielectric constant 1011~
1013 was a mean feature of such materials. The dielectric constant exhibits a
sharp peaking behavior for some samples. The conduction mechanism was
investigated and found to be multiple hopping conduction mechanism.
