abstract |
Dielectric and magnetic properties of the Bi1-x-yGdxLayFe1-yTiyO3 (x=0.1 and y=0.0, 0.1, 0.2, 0.3 and 0.5) solid solution ceramics have been presented this work. Effects of La substitution on the structural, electrical and ferroelectric properties of Bi1-x-yGdxLayFe1-yTiyO3 samples have been studied by performing X-ray diffraction and dielectric measurements as well as characterizing M-H hysteresis loop. The results indicate that, when La content exceeds 0.2, the crystal structure of the ceramic samples changes from rhombohedral to tetragonal phase. The maximum ferroelectric transition temperature (T-c) of this system was 190 degrees C with the dielectric constant peak of 2500 at 100 kHz for y=0.5. With increasing La content, the remanent magnetization increases and the coercive magnetic field decreases. (C) 2013 Elsevier Ltd. All rights reserved. |
