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 ...
(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 ...
