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 ...
Synthesis and microwave dielectric properties of Sr3Zn1−xMgxNb2O9 phases
Oxides of the type, Sr3Zn1−xMgxNb2O9 (0≤x≤1) have been obtained by the ceramic method. These oxides crystallize in the hexagonal cell corresponding to ordered triple perovskites. Sintered disks show nearly frequency-independent ...
