Outline of Final Research Achievements |
I have carried out the single crystal growth of double perovskite manganites, and the measurement of the electrical and magnetic properties of these samples. In this study, I succeeded the single crystal growth of the double perovskite manganite for almost rear earths, and the observation of an anomaly of the temperature dependence of the dielectric constant at magnetic phase transition. This anomaly depend on an applied magnetic field. I think these results clearly show the strong coupling between the dielectric and the magnetic properties of the double perovskite manganite.
