Electrical and magnetic properties of NiTiO3 nanoparticles synthesized by the sol–gel synthesis method and microwave sintering

Abstract

In this paper, we focused on microwave sintered NiTiO3 nanoparticles synthesized via sol–gel method. The crystal structure was determined by the X-ray diffraction. Vibrational bands related to Ni–O and Ti–O bands were confirmed using the Fourier transform infrared spectrum. These NiTiO3 ceramics obeyed semiconductor behavior of Arrhenius type. The activation energy was found to be 0.04 μeV. The M–H curve exhibited superparamagnetic behavior at room temperature. Keywords: NiTiO3, X-ray diffraction, HRSEM, Impedance analysis, M–H curve
