Magnetic nanoparticles attracted a great deal of attention in the medical applications due to their unique properties. The most exceptional property of magnetic particles is their response to a magnetic force, and this property has been utilized in applications such as drug targeting, bioseparation, contrast agents in magnetic resonance imaging (MRI) and heating mediators for cancer therapy. In...

Nickel–zinc ferrites are some of the most interesting soft magnetic materials. They have been extensively used in a number of electronic devices because of their low magnetic coercivity, low eddy current related to their high electrical resistivity, and they are especially suitable for high–frequency applications (large permeability). New low-temperature synthesis methods have been developed to...

Firstly nickel ferrite nanoparticles were synthesized via a simple precipitation method. Then mono-disperse platinum nanoparticles and NiFe2O4@TiO2/Pt nanocomposites were synthesized by a facile sol-gel procedure. The structure, phase and crystallite size of the magnetic and photo-catalyst products were characterized by X-ray diffraction pattern (XRD). The morphology and size of the nanostructu...

Nickel zinc ferrite nanoparticles (Ni0.20Zn0.44Fe2.36O4) have been produced at room temperature, without calcination, using a reverse micelle process. Particle size is approximately 7 nm as determined by x-ray powder diffraction and transmission electron microscopy. Saturation magnetization values are lower than anticipated, but are explained by elemental analysis, particle size, and cation occ...

Nickel ferrites have been extensively studied due to their numerous applications in electronic devices, microwave adsorbents, corrosion protectors, magnetic fluids and catalysts [1-5], among others. Nickel ferrite is a soft material with inverted spinel with the tetrahedral site (A) occupied by Fe and the octahedral site occupied by Fe and Ni. It is applied to devices that require easy magnetiz...

MnZnFe2O4 ferrite nanoparticles were prepared by co-precipitation method using a microwave heating system at temperature of 100 C. X-ray diffraction reveals the samples as prepared are pure ferrite nanocrystalline phase, transmission electron microscopy image analysis shows particles are in agglomeration state with an average size of about 10 nm, furthermore, crystal size of samples are increas...
