Abstract
Manganese Zinc Ferrite Mn0.6Zn0.4NdxFe2-xO4 (x = 0.04, 0.05, 0.06, 0.07 and 0.08) nanoparticles doped with rare-earth ions of Neodymium (Nd+3) were synthesized using combustion method. The single spinel phase formation without any impurity was characterized using X-ray diffraction (XRD) technique and Infra-Red (IR) spectroscopy. Lattice constants ‘a’ show variation with Nd+3 doping. Particle sizes using TEM were found in the range of 5 nm–25 nm. Systematic alteration of saturation magnetization (MS) can be achieved by changing Nd+3 concentrations in the samples. These variations can be attributed to the inclusion of rare earth metal ions replacing Fe+3 in the matrix. Nd+3-Fe+3 interactions possibly improving the alignment of moments on B-sites leading to a decrease in the canting angle which in turn increases MS Relative to undoped Manganese Zinc ferrite samples.
