Electrical and magnetic properties of NiTiO 3 nanoparticles synthesized by the sol–gel synthesis method and microwave sintering

摘要

In this paper, we focused on microwave sintered NiTiO3nanoparticles 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 NiTiO3ceramics obeyed semiconductor behavior of Arrhenius type. The activation energy was found to be 0.04μeV. The M–H curve exhibited superparamagnetic behavior at room temperature.
