The rich physical properties have made Nano particles of spinal ferrites to be of great interest in fundamental science. Nano Nickel Cobalt ferrite particles were prepared by sol- gel method under stoichiometric conditions which were later Calcinated at 500ºc. Here we add a magnetic dopant Co to nickel ferrite Nano crystals and characterize how relevant properties of the samples are modified accordingly. Basically, the doping causes a rearrangement of Fe+3 ions into the two pre-existing octahedral and tetrahedral sites. Thermal behaviour of the dried gels was studied by Thermogravimetry…mehr

The rich physical properties have made Nano particles of spinal ferrites to be of great interest in fundamental science. Nano Nickel Cobalt ferrite particles were prepared by sol- gel method under stoichiometric conditions which were later Calcinated at 500ºc. Here we add a magnetic dopant Co to nickel ferrite Nano crystals and characterize how relevant properties of the samples are modified accordingly. Basically, the doping causes a rearrangement of Fe+3 ions into the two pre-existing octahedral and tetrahedral sites. Thermal behaviour of the dried gels was studied by Thermogravimetry Analysis. The structural and morphological properties of the spinal ferrite sample have been investigated by means of X-ray diffraction studies, Scanning Electron Microscope and the Transmission Electron Microscopy. The functional groups of the magnetic material were identified from FT-IR spectroscopy. To study properties of materials VSM, MATLAB and LCR were used. The magnetic properties were examined by using Vibrating Sample Magnetometer studies. X-ray results confirm the single-phase cubic spinal structure. Electrical properties were evaluated using LCR meter.
