Giant dielectric properties of CaCu3Ti4O12 (Li,Ti) -doped NiO composites subjected to postsintering annealing and compressive stress
We report the effects of postsintering annealing in argon and compressive prestress on the giant dielectric properties of CaCu3Ti 4O12 - Li0.3Ti0.02 Ni 0.68O composites in the frequency range from 100 Hz to 1 MHz. After postsintering annealing, all compounds investigated still display a Debye-like r...
