Abstract

We investigated synthesis, structure, composition as well as electric and magnetic properties of copper tantalum oxide single crystals and powder samples. It was possible to flux-grow single crystals of undoped Cu2Ta4O12. To modify the copper content in this structure, tetravalent and hexavalent ions like titanium and tungsten have been incorporated. Rietveld refinement data as well as magnetic and dielectric properties are presented.
