Research Abstract |
We have succeeded in obtaining high-quality polycrystalline samples of perovskite Eu_<1-x>Y_xMnO_3 and Y_<1-x>Y_xMnO_3 by a high pressure technique with using single crystalline precursors of the ambient pressure phase. Complete multiferroic phase diagram of orthorhombic RMnO_3 was established. Furthermore, we have found that the magnetoelectric response is enhanced near the bicritical phase boundary. Single crystals of perovskite YMnO_3 were successfully grown under high pressure with a quasi hydrothermal condition. By using a synchrotron x-ray, we have observed for the first time ferroelectric lattice displacement driven by a magnetic order in YMnO_3.
