Investigation of structural and electrical properties of NdFeO3 perovskite nanocrystalline

The permittivity, impedance and AC conductivity studies of NdFeO₃ perovskite nanocrystalline material were performed in the frequency range 1 kHz–100 kHz, and temperature range 100 K–320 K. The Sol–gel auto-combustion technique employed to synthesis NdFeO₃ perovskite compound. The X-ray diffraction (XRD) pattern of NdFeO₃ indicating the single-phase orthorhombic structure. The Scanning electron microscopy (SEM) image shows that the grains homogeneously spread throughout the surface morphology. The average grain size found to be 50 nm. The P–E loop suggests that the NdFeO₃ material is ferroelectric in nature. An impedance spectroscopy study suggests that the negative temperature coefficient of resistance (NTCR) behavior of the material. The conductivity spectrum follows the Jonscher's law.
