Our research in this field aims at the investigation and preparation of new materials that are possible building blocks for tomorrow's electronics and other technologies. Our main goal is achieving a better understanding of exotic properties like multiferroicity or colossal dielectric constants. For this purpose, we perform fundamental research on these materials covering a broad parameter space like temperature, frequency, or magnetic field.
