Outline of Final Research Achievements

We aimed to find novel and interdisciplinary properties of materials across the research fields of dielectics, conductivity, magnetism and semiconductors, which lead to open new fields in material science, by exploiting the structural flexibility and controllability of molecular materials. As a result, we obtained the following achievements across these fields; the discovery of novel electric and magnetic excitations in a charge-transfer type of ferroelectric, the creation of a research field of electronic glasses, the discovery of anomalous correlation effects in massless Dirac electrons, and the discovery of the coexistence of a spin-liquid and a metal. These achievements are expected to be seeds for future interdisciplinary researches in material science.
