| Abstract: | Single phase perovskite-type cubic ceramics of Pb[(Mg3/4Cu1/4)1/3Nb2/3]O3 (PMCN) were synthesized by high temperature double step solid state reaction technique. Dielectric studies show relaxor behaviour with diffuse phase transition. The phase transition (Tm) occurs at -22°C at 10 kHz. The frequency dependence of Tm has been modeled using Vogel-Fulcher relation. The dielectric relaxation in PMCN is found analogous to the magnetic relaxation in spin-glass system. The relaxor behaviour in PMCN has also been examined through admittance spectroscopy. |
