15 صفحه اولANALYSIS OF SOME MAGNETIC PROPERTIES OF DILUTED MAGNETIC SEMICONDUCTORS
The susceptibility and specific heat experimental results of the diluted magnetic semiconductors (DMS) are incorporated in a model based on short-range as well as long-range interaction in a random may of magnetic ions. The so-called nearestneighbor pair approximation (NNPA) is applied. It appears that the calculated values of zero field specific heat and Curie-Weiss temperature based on th...
متن کاملStructure and Magnetic Properties of Oxide Nanoparticles of Fe-Co-Ni Synthesized by Co-Precipitation Method
Oxide nanoparticles of Fe-Co-Ni were prepared in six different compositions by co-precipitation method. The as-synthesized nanoparticles were characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electron microscope (FESEM), Fourier Transform Infrared (FT-IR) and Vibrating Sample Magnetometer (VSM). It was found that the nanoparticles had mean crystalline size of 30-55 nm and spher...
متن کاملEffect of solvent’s types on the structure and magnetic properties of the as-coprecipitated Fe3O4 nanoparticles
Magnetite (Fe3O4) nanoparticles were synthesized by coprecipitation route. Coprecipitation is a simple, reproducible and accessible technique relying on the coprecipitation of Fe2+ and Fe3+ cations by NaOH as base at low temperature (~80 °C). In this work, the role of different solvents (H2O, ethylene glycol, diethylene glycol, triethylene glycol) on phase, structure, microstructure and magneti...
متن کاملSTRUCTURE AND MAGNETIC PROPERTIES OF SiO
Magnetic nanoparticles for applications in separation and purification processes must satisfy several basic requirements. They should be superparamagnetic, i.e. possess low coercivity (H c ) and low retentivity (M r ), to enable re-dispersion after magnetic capture. In this study, the synthesis of SiO 2 coated γ-Fe 2 O 3 nanocomposite particles has been attempted to achieve the above magnetic p...
