Abstract :
Dielectric properties of Ca2TiMnO6 (CTM) were systematically investigated. Our results revealed that (1) the observed relaxation does not feature one clear Arrhenius behavior, (2) the peak intensity of the imaginary part of the complex permittivity can be well expressed by a relation similar to the Fermi–Dirac distribution function, and (3) the colossal dielectric behavior of the sample can be well understood based on the framework of universal dielectric response. These features indicate that the dielectric properties of CTM are related to polaron relaxation.
