CaCu 3 Ti 4 ร x Fe x O 12 (0 rx r 0.2) ceramics were fabricated by a solid-state reaction method, and the dielectric properties were studied. Dielectric measurement performed at room temperature shows that with Fe content increasing from 0 to 0.2, the dielectric constant (e 0 ) decreases from about
## Abstract CaCu~3~Ti~4โ__x__~ Nb__~x~__ O~12~ (__x__ = 0, 0.01, 0.08, 0.2) ceramics were fabricated by a conventional solidโstate reaction method. The ceramics showed the bodyโcentered cubic structure without any foreign phases and the grain size decreases with Nb doping. Two Debyeโtype relaxation
## Abstract We have developed a novel route to reduce the dielectric loss of CaCu~3~Ti~4~O~12~ (CCTO) material based on the internalโbarrierโlayerโcapacitance (IBLC) model. By the partial LaโforโCa substitution the dielectric loss was suppressed reโmarkably while the giant dielectric constant still
