Complex rare-earth titanates with the perovskite structure: Rietveld studies and dielectric properties
Several new compositions of the type (Ln2/5Ba2/5Ca1/5)(Cd2/5Ti3/5)O3 and (Ln1/3Ba1/3Ca1/3)(Cd1/3Ti2/3)O3 (Ln = La, Nd, Sm, Gd, Dy) pertaining to the perovskite structure have been investigated. We have also tried to ...
(La0.4Ba0.4Ca0.2)(Mn0.4Ti0.6)O3: A new titano-manganate with a high dielectric constant and antiferromagnetic interactions
A new perovskite-based titano-manganate, (La0.4Ba0.4Ca0.2)(Mn0.4Ti0.6)O3, has been prepared by the ceramic route at 1100°C. This oxide was found to possess the cubic perovskite structure with ‘a’=3.9477(23) Å (space group ...
Effect of pre-sintering temperature on the structural and dielectric properties of (Ba0.5Sr0.5)TiO3 thin films deposited by sol–gel technique
(Ba0.5Sr0.5)TiO3 thin films have been deposited by sol–gel technique and the effect of pre-sintering temperature on the structural and dielectric properties has been studied. The sol was prepared from barium acetate and ...
Dielectric, piezoelectric and pyroelectric properties of PMN–PT (68:32) system
Solid solution of 32 mol% of Lead Titanate in PMN–PT system has been prepared by columbite precursor method. Room temperature X-ray diffraction study reveals the formation of perovskite phase with tetragonal structure. ...
