Magnetic properties of Nd-doped strontium ferrite nanoparticles abstract
Nano sized Nd-doped strontium ferrites, SrNdxFe12-xO19, with x=0.0-0.5, were successfully prepared through a chemical coprecipitation process. The samples were characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF) and vibrating sample magnetometer (VSM). Various parameters such as lattice constants (a and c) and crystallite size were calculated from the XRD data. The crystallite size was in the range of 28-39 nm. The specific saturation magnetization (Ms) and the coercivity (Hc) of strontium ferrites could be improved by substitutions of Nd3+ ions on Fe3+ ion basis sites. The Ms revealed magnetic behavior with respect to Nd3+ ions concentration, showing a decrease. The Hc increased with increasing Nd3+ ions concentration.
