MnZn ferrite precursor powders were prepared by the nano in situ composite method. Three surfactants, which include polyethylene glycol 400 (PEG-400), cetyltrimethyl ammonium bromide (CTAB), and sodium dodecyl sulfate (SDS), usedM impact of surfactants on sol solutions was studied. X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Raman a field emission scanning electron ...

Nano-sized crystallites of iron oxide were synthesized by cost effective co-precipitation method. X-ray diffraction pattern indicated that the magnetic nanoparticles were pure Fe3O4 with a spinel structure. The nanoparticles were characterized by X-ray diffraction (XRD), Fourier-Transform Infrared (FT-IR) spectra, Transmission electron microscope (TEM) and magnetization measurement of the nanop...

Recently, it has been shown that it is feasible to realize 29.5 Gb/in recording density employing hexagonal barium ferrite (H-BaFe) nanoplatelets [1]. Although H-BaFe nanoplatelets are a potential candidate for high density recording media, their greatest disadvantage is their dispersibility and agglomeration by forming poker-chip-like stacks due to mutual magnetic interactions [2-3]. To achiev...

The magnetic properties of nano-crystalline CoMxFe2 xO4 (where M=Gd and Pr and x 1⁄4 0; 0.1 and 0.2) powders prepared by a citrate precursor technique have been studied by using vibrating sample magnetometer (VSM). The crystallite sizes of the materials were varied by altering the synthetic conditions and are within the range of a minimum of 6.8 nm and a maximum of 87.5 nm. The materials were c...

A small FMR ferrite disk strongly perturbs the cavity field. Graphical representation of the Poynting vector shows that due to the vortex structure the absorption cross-section of a ferrite particle can be much bigger than its geometrical cross-section. Spectral properties of magnetic oscillations in a ferrite disk show unique vortex structures for MS-wave functions.

Spinel copper ferrite (CuFe2O4) and zinc ferrite (ZnFe2O4) nanoparticles were synthesized using a sol-gel self-combustion technique. The structural, functional, morphological and magnetic properties of the samples were investigated by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Transmission electron microscopy (TEM) and vibrating sample magnetometry (VSM). XRD patte...
