Temperature dependence of dielectric polarization and strain behaviors for rhombohedral PIMNT single crystal with different crystallographic orientations

► PIMNT single crystal was grown with the composition selected as PIMNT35/35/30. ► The phase transition temperature TC and Trt were improved significantly. ► The polarization data of PIMNT in a wide temperature range were revealed. ► The intermediate metastable state was induced at an electric field of 12.5 kV/cm.
