Bi(Ni<SUB>0.5</SUB>Ti<SUB>0.5</SUB>)O<SUB>3</SUB> (BNT) ceramics with a perovskite structure, which were almost impossible to fabricate under atmospheric pressure, were synthesized at a high pressure of 6 GPa using a multianvil-type high-pressure apparatus. It was confirmed that the synthesized samples had a multidomain structure and ferroelectricity on the basis of scanning nonlinear dielectric microscopy (SNDM) and polarization–electric field (<I>P</I>–<I>E</I>) hysteresis loop measurements.
