Objectives: The current research work was investigated magnetic properties of Fe2O3-Bi2O3-TiO2 nanoparticles (NPS). Methods/Statistical analysis: The Fe2O3-Bi2O3-TiO2 has been synthesized by a simple precipitation method. The samples were characterized by X-ray powder diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), Fourier-Transform Infrared Spectroscopy (FTIR) and UV-vis. absorption (reflectance) spectra. The magnetic properties of the magnetite nanoparticles were calculated by vibrating sample magnetometer (VSM) at ambient temperature. Findings: The effect of calcination on the magnetic and structural properties of Fe2O3-Bi2O3-TiO2 nanoparticles was studied. The Fe2O3-Bi2O3- TiO2 nanocrystal was subjected to calcination up to 200◦C, magnetite was converted to magnetite; the second transition was in the range of 300-400◦C which changed it to hard ferromagnetic hematite. Application/Improvements: This research provides promising results concerned with magnetic sensing probes for magnetic resonance imaging for in-vitro diagnostics and contrast agents.
