Abstract

Nanoparticles of Ni0.4Mg0.4Cd0.2YyFe2-yO4 (where y= 0.025, 0.050, 0.075, 0.100 and 0.125) were synthesized by a simple and less cost effective method involving sol-gel auto combustion at low temperature. Metal nitrates, such as Yttrium nitrate, Nickel nitrate, Cadmium nitrate, Magnesium nitrate and Ferric nitrate, were used as the source materials. Citric acid was used as the burning agent. The pH of the precursor was maintained at 7. The prepared samples were sintered for 400 oC. Structural and magnetic properties of nano-crystalline ferrite powders have been investigated using XRD and VSM. The role of Yttrium substituted Nickel-Magnesium-Cadmium shows the formation of crystal phase, which was identified by X-ray diffraction method. The lattice constants decrease with the increasing in Y3+ and decrease in Fe contain. We report the synthesis of nanoparticles, soft and spinel with crystalline size is in the range of 23.092 to 17.02nm. The Vibrating Sample Magnetometer was used to obtain the Hysteresis parameters. The magnetic property of the prepared samples shows remarkable changes with changes the Y3+ percentage.
