Synthesis and dielectric characteristics of La0.5Bi0.5MnO3 ceramics
Source abstract
Abstract
La0.5Bi0.5MnO3 ceramics with a single phase were prepared by a solid-state reaction method, and their dielectric properties were characterized. Two dielectric relaxations with a giant dielectric constant were identified in the temperature range from 125 to 350 K. The electron hopping between Mn3+ and Mn4+ was found to be the origin of the dielectric relaxation at low temperatures (125–200 K) with an activation energy of 0.18 eV. The high temperature (200–350 K) dielectric relaxation can be attributed to the conduction.
