By a News Reporter-Staff News Editor at Journal of Technology -- Fresh data on Magnetics are presented in a new report. According to news reporting out of Shiraz, Iran, by VerticalNews editors, research stated, "Cobalt ferrite nano-particles, Co0.9RE0.1Fe2O4, with three different rare earth ions (Nd, Eu, and Gd) were prepared by the chemical co-precipitation method. X-ray diffraction (XRD) analysis, transmission electron microscopy (TEM), Fourier Transform Infrared (FTIR), and Vibrating Sample Magnetometry were carried out to study the structural and magnetic properties, respectively."
Our news journalists obtained a quote from the research from the Shiraz University of Technology, "The XRD results revealed that the crystal size is about 22 nm for Gd-Co ferrite, which is close to the particle sizes observed from TEM images (20 nm). The FTIR measurements between 350 and 4000 cm(-1) confirmed the intrinsic cation vibrations of the spinel structure. The results showed that the RE ions increase both vibrational frequencies and bond strength. The magnetic results showed that the highest magnetic coercivity and the loop area correspond to the Gd-Co ferrite, making it suitable for hyperthermia treatment."
According to the news editors, the research concluded: "Also, the Curie point was decreased by the RE ions and had its lowest value for Nd-Co ferrite (336 degrees C)."
