| Popis: | Ultrafine powders of nano-crystalline rare earth (Gd+3) doped manganese cobalt ferrite with composition Mn0.5Co0.5Fe2-xGdxO4 (x = 0.00, 0.02, 0.04, 0.06, and 0.08) were synthesized using combustion synthesis. Powders obtained through the combustion process were characterized using X-ray diffraction and Fourier transform infrared spectroscopy for structural analysis. Particle size was determined using a Transmission electron microscope (TEM) and was seen to remain in narrow range of 15 nm–30 nm with increasing Gd+3 concentrations. The magnetic alterations triggered by Gd+3 incorporation were studied using a vibrating sample magnetometer (VSM) which showed that the magnetic parameters such as Saturation magnetization (MS) and Coercivity (HC) of the nano-powders depend remarkably on Gd+3 concentrations in the ferrite unit cell. The electrical transport properties such as DC resistivity and dielectric constant were also seen to depend on the extent of rare earth doping in the ferrite material. |
