Abstract

 NANO-SIZED COBALT FERRITE (COFE2O4) SYNTHESIZED BY NOVEL SOLUTION SOL-GEL AUTO COMBUSTION METHOD FROM METAL NITRATES AND CITRIC ACID WITH A FINAL PH VALUE OF 7. X-RAY DIFFRACTION PATTERN (XRD) AND TRANSMISSION ELECTRON MICROSCOPE (TEM) RESULTS SHOWED THAT THE SYNTHESIZED POWDER HAS NANOSCALE AND ALSO SPHERICAL SHAPE. ALSO MAGNETIC MEASUREMENTS OF COFE2O4 NANOPOWDER WERE PERFORMED USING A VIBRATING SAMPLE MAGNETOMETER (VSM) AND SATURATION MAGNETIZATION WAS 77.09 EMU/G AT AT MAGNETIC FIELD OF 8 KOE.
