| Research Abstract |
We have reported the dielectric behavior of an electronic origin in RFe_2O_4-derived materials and perovskite manganese oxides ; this origin is entirely different from the ordinary ion-displacement mechanism. Such dielectric materials can be used for the fabrication of fatigue-free devices. In addition, some of these materials show high dielectric constants and can be prepared in a simple solid state method in air, the properties which are favorable to application.
