Journal ArticleDOI
Impedance and AC conductivity study of nano crystalline, fine grained multiferroic bismuth ferrite (BiFeO3), synthesized by microwave sintering
TL;DR: In this article, a microwave sintered nanocrystalline BiFeO3 (BFO) ceramic was used to reduce the sintering time and increase the final density.
Journal ArticleDOI
Structural, electrical, magnetic and magnetoelectric properties of Fe doped BaTiO3 ceramics
TL;DR: In this paper, structural, electrical, magnetic and magnetodielectric properties of BaTi 1− x Fe x O 3 (0%≤ x ≤ 10%) ceramics have been investigated.
Journal ArticleDOI
Phase formation, microstructure, electrical and magnetic properties of Mn substituted barium titanate
TL;DR: The phase transition from tetragonal to hexagonal takes place at x = 1% concentration and complete hexagonal phase is obtained for x ≥ 5% for doped barium titanate (BaTi 1− x Mn x O 3 ) ceramics with x = 0, 1, 2.5, 5, 7.5 and 10% have been synthesized by a solid state reaction method.
Journal ArticleDOI
Dielectric properties of A- and B-site doped BaTiO3: Effect of La and Ga
Devidas Gulwade,Prakash Gopalan +1 more
TL;DR: In this article, the influence of individual dopants, namely La and Ga, on the dielectric properties of BaTiO 3 has been investigated and a solid solution of the type Ba 1 −3 x La 2 x Ti 1−3 y Ga 4 y O 3 have been investigated.
Journal ArticleDOI
Diffuse phase transition in La and Ga doped barium titanate
Devidas Gulwade,Prakash Gopalan +1 more
TL;DR: In this paper, the phase transitions in BaTiO3 and Ba1−xLaxTi 1−xGaxO3 ( y = 0.008, 0.012, 0.016 and 0.02) have been studied by high temperature X-ray diffraction (HTXRD) and Raman spectroscopy.
