The Dielectric Properties of Some Studied Ferrites
Hesham Zaki
In present chapter, AC conductivity and dielectric studies of Lio.5+0.5xGexFe2.5-1.5x (x = 0.0, 0.2, 0.3 & 0.5), Cu1+xGexFe2–2xO4 (x = 0.0, 0.2, 0.3, 0.4), Cu1+xTixFe2–2xO4 (x = 0.0, 0.2, 0.3, 0.4), and CuxFe3−xO4+δ (0.0, 0.4, 0.6, 0.8 and 1.0) spinel ferrites have been covered. The relation of log conductivity and log activation energy for Lio.5+0.5xGexFe2.5-1.5x ferrites showed a straight line between l04 Hz to l06 Hz. The dielectric properties for Ge substituted and Ti substituted Copper ferrites were explained using the Maxwell–Wagner model.
