Multiferroic ceramics Pb(Fe1/2Nb1/2)O3 doped by Li

Abstract

We present the results of obtaining and investigating multiferroic ceramics Pb(Fe1/2Nb1/2)O3 (PFN) and PFN doped by various amounts of Li (PFN:Li). Ceramics have been obtained from oxides by two-step synthesis. For obtained samples the X-ray diffraction patterns, microstructure, DC electric conductivity, the temperature dependencies of dielectric permittivity and dielectric losses, electromechanical properties and hysteresis loops have been investigated. Obtained results have shown that the introduction of Li decreases electric conductivity and improves dielectric and electromechanical parameters important for applications.
