Polycrystalline Bi(MgTi)O samples were prepared under high pressure. A mixed powder of Bi
O, TiO and MgO with a prescribed ratio was packed into platinum cell and was heated a cubic anvil-type apparatus at 6.5 GPa and 1000 
C. The obtained samples were characterized by powder X-ray diffraction measurements. Although some impurity peaks existed, the main peaks were perovskite peaks. The structure of Bi(MgTi)O is rhombohedral, as well as BiFeO. The D-E hysteresis loop was not saturated due to the impurities, but the possibility as ferroelectric can be expected enough.

The antiferroelectric crystal can become very useful ferroelectric by combining with other ferroelectric though is only by it a wonderful, electric characteristic. It was reported to synthesize Bi(MgTi) O by the high temperature high pressure synthesis by Khalyavin though it was one of bisumuth perovsukite, and the synthesis was difficult in the normal pressure. Bi(MgTi) O was collected in a method similar as for us and when the high temperature high pressure was synthesized, the sample that became rhombohedral structure a room temperature was able to be collected. When the P-E hysteresis loop of this sample was measured, the result of suggesting hysteresis strong dielectric feature. It was found that the rhombohedral structure is the metastable phase though it was stable phase in the high pressure.
