Anomalous Dielectric Behavior in A-site Ordered Perovskite CaCu^sub 3^Ti^sub 4^O^sub 12^ : Effect of A'-site Doping

The effect of partial replacement of Cu ions by small Be cations with no d-electrons in ... ceramics was studied over the temperature range from 90 K to 800 K. Dielectric constant of ... decreases exponentially with increasing x as e' =4000 + exp(-x/0.023); by 5% of Be-doping, the relaxation ti...
