Cu 0.5 Ti 0.5 Tb x Fe 2-x O 4 samples were prepared by powder technology at different values of x (0, 0.03, 0.06, and 0.09). The behavior of dielectric constant studied within frequency range (100 Hz - 10 MHz)) at different annealing temperatures (298, 373, and 473) K. This studying indicated a fine behavior for dielectric constant with frequency range and annealing temperatures. The study of dielectric loss (tan δ) showed reducing of relaxation time and appearing different loss peaks with the variation of frequency and temperature. Also the activation energy which is related to relaxation time is calculated.
