摘要：

Polycrystalline material of double perovskite Dy2NiMnO6 was successfully synthesized by a high-temperature solid-state reaction method. Preliminary X-ray investigation established the formation of compound with monoclinic structure. The material exhibits dielectric relaxation supported by modified Curie-Weiss law and a Vogel-Fulcher law. Impedance spectroscopy of the compound was analyzed by impedance analyzer in the range of frequency (1kHz-1MHz) and temperature (25-250 degrees C) that confirming non-Debye type of relaxation. The presence of different kind of charge carriers along with NTCR behavior of the material was found from the AC conductivity study. It is noticed that oxygen vacancies are the responsible factor for high temperature conduction process and dynamics of polarization of system. From these results, it may be concluded that this compound may have extreme potential applications at different temperatures.
