[ 1 ] - The Effects of Cu and Zn Dopants on Phase Constituents, Magnetic Properties and Microstructure of Nickel Ferrite
In this research nanoparticles of Ni0.55Zn0.35Cu0.1Fe2O4 were synthesized by sol–gel auto-combustion method. Changes in phase constituents, microstructure and magnetic properties as a result of Zn and Cu additions were evaluated by X-ray diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM), and Vibration Sample Magnetometer (VSM) techniques. XRD results show that the doped sam...
[ 2 ] - Coprecipitation Synthesis of CoFe2O4 Nanoparticles for Hyperthermia
Cobalt ferrite (CoFe2 O4 ) nanoparticles have attracted significantly attentions for spintronics, recording media and bioapplications due to their unique magnetic and chemical properties. In this work, single phase CoFe2 O4 nanoparticles were synthesized at various coprecipitation temperatures (60, 80 and 90 °C) without post calcination. The effects of oleic acid as surfactant on the microstruc...
[ 3 ] - EFFECT OF PH CHANGES ON PHASE CONSTITUENTS, MICROSTRUCTURE AND MAGNETIC PROPERTIES OF NANO-SIZED NiFe2O4 POWDER SYNTHESIZED BY SOL–GEL AUTO-COMBUSTION METHOD
Nano-sized NiFe2O4 powders were synthesized by sol–gel auto-combustion method using pH values from 7 to 9 in the sol. The effect of pH variations on complexing behavior of the species in the sol has been explained. Changes in phase constituents, microstructure and magnetic properties by changes in pH values were evaluated by X-ray diffraction (XRD), field emission scanning electron micros...
