Zinc ferrite nanoparticles as MRI contrast agentsw

Magnetic resonance imaging (MRI) is a powerful clinical imaging technique for the non-invasive diagnosis and posttherapy assessment of a variety of diseases. MRI contrast can be enhanced by the use of positive or negative contrast agents resulting in brighter (T1-weighted) or darker (T2-weighted) images, respectively. Superparamagnetic iron oxide (SPIO) nanoparticles are T2 contrast agents that...

The Zinc-Ferro Ferrite System Revisited

Highly stoichiometric zinc ferrous ferrites Zn,F+,O, were prepared and characterized by magnetization, desacwmmodation, electrical conductivity, thermal expansion and magnetostriction measurements. The results of the magnetization measurements indicate that up till x = 0.5 the magnetic structure is collinear, which led to the highest saturation magnetizations ever found in spinel femtes. The th...

Synthesize of Superparamagnetic Zinc Ferrite Nanoparticles at Room Temperature

Superparamagnetic single phase zinc ferrite nanoparticles have been prepared by coprecipitation method at 20 °C without any subsequent calcination. The composition, crystallite size, microstructure and magnetic properties of the prepared nanoparticles were investigated using X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), transmission electron microscope (TEM)...

Synthesis and Characterization of Nickel Zinc Ferrite Nanoparticles

In this research nickel zinc ferrite nanoparticles with composition of Ni1-xZnxFe2O4 (where x=0, 0.3, 0.7, 1) were synthesized by a sol-gel method at 600 °C for 5 hours. The structure of nanoparticles was studied using X-ray diffraction pattern. The lattice parameter of ferrite nanoparticles was calculated and indicates lattice constant of nanoparticl...

Neutron Diffraction and Mössbauer Studies of Zinc Ferrite

It is shown by neutron diffraction and Mossbauer spectrometry that the formation of a long range magnetic order in zinc ferrite depends sensitivily on the content of divalent iron. The experimental data favour a non collinear model of the magnetic structure. Zinc ferrite is a normal spinel with the tetrahedral A sites occupied by Zn2+ ions and the octahedral B sites occupied by Fe3+ ions. Any m...
