This paper presents new physical properties of nanocrystalline SnFe2O4 ferrites, synthesized by co-precipitation method. Magnetization measurement indicates superparamagnetic behavior; the blocking temperature is about 300 K. We performed X-ray diffraction, infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), Energy Dispersive Spectroscopy (EDS), UV-visible measurement, superconducting quantum interference device (SQUID) and zero-field-cooled (ZFC)/field-cooled (FC… 
Magnetic and photocatalytic properties of Ni–Co ferrites
The effects of synthesis conditions on the magnetic properties of zinc ferrite spinel nanoparticles
Zinc ferrite nanocrystals were synthesized from metal chloride precursors via chemical co-precipitation method, using different synthesis conditions. Characterization measurements including X-ray
Experimental and first-principles study of the origin of the magnetic properties of CoFe2O4 spinel ferrite
CoFe2O4 nanoparticles were prepared by the co-precipitation method, the structural properties were performed using X-Ray Diffraction (DRX) in the goal to prove the success of Cobalt ferrite formation


Synthesis of Highly Crystalline and Monodisperse Cobalt Ferrite Nanocrystals
Highly crystalline and monodisperse cobalt ferrite nanocrystals were fabricated by the high-temperature aging of a metal−surfactant complex followed by mild oxidation. Particle sizes were varied from
Enhanced Optical Properties of Ag–TiO2 (Rutile) Hybrid Nanopowder
A strong surface-enhanced Raman scattering (SERS) from TiO 2 nanoparticles is firstly obtained in a nanostructural Ag-TiO 2 calabash-like hybrid particle powder synthesized by γ-radiation combined
Raman and Fourier-transform infrared photoacoustic spectra of granular ZnO2
Raman and Fourier-transform infrared photoacoustic spectra of nanometer-sized grains of monoclinic ZrO2 (5-80 nm) at room temperature are reported. A characteristic peak around 1040 cm(-1) is
Mössbauer spectroscopic properties of tin-doped iron oxides
The 57Fe Mössbauer spectra recorded in situ from tin-doped Fe3O4 at elevated temperature in vacuo shows the Curie temperature to decrease with increasing concentrations of the dopant. Thermal
Oxide Magnetic Materials
Manganese-zinc ferrites are provided consisting essentially of manganese oxide, zinc oxide and iron oxide and small but effective amount of stannic oxide and lithium oxide ranging up to about 3.2
Improved Voltammograms of Hydrocaffeic Acid on the Single-Walled Carbon Nanotube/Graphite-Film Surfaces
This dissertation aims to provide a history of Islamic Azad University in Karaj from 1989 to 2002, a period chosen in order to explore its roots as well as specific cases up to and including the year of Shahid Beheshti's death.
