Abstract
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. Keywords: Fe2O3-Bi2O3-TiO2 NPs; Magnetic Properties; XRD; FESEM; VSM

The use of nanomaterials for water purification has become an interesting research area in recent years
The well-defined diffraction peaks are approximately 25, 38, 48, 54, 54, 54, 62, 68, 70, 70, 70, 74, and 82, which are assigned to the crystal planes [101], (004), [200], [105], [211], [204], [116], [220], [215] and [224] respectively. This characteristic pattern of the X-ray powder diffraction (XRD) is consistent with the typical anatase TiO2 JCPDS values (JCPDS Card No 21-1272)
The prepared NPs were characterized by XRD, Fourier transform infrared spectra (FT-IR), FE-SEM, UV-DRS spectra, and vibrating sample magnetometer (VSM), The XRD pattern of NPS shows the anatase phase, the obtained data from UV-Visible absorption spectra indicated that it was achieved through the process of Fe2O3 & Bi2O3 co-doping with TiO2
Summary
The use of nanomaterials for water purification has become an interesting research area in recent years. Nanomaterials are a growingly important nanotechnology products. They contain nanoparticles in at least one dimension which are smaller than 100 nm. These nanomaterials are coming into health care, electronics, cosmetics and other areas [1,2]. Due to many potential innovative applications, Nanoparticles research has received considerable attention. They have unique and novel magnetic, optical, electronic and catalytic properties [3]
