Description
Summary:The effect of doping strontium in structural and magnetic properties of co-precipitated strontium cobalt ferrite (SrxCo1-xFe2O4) nanoparticles are discussed in this paper. The mole of strontium ions was used for doping are 10% of mole cobalt. The synthesis was conducted at a temperature of 95°C with following post annealing at 600°C for five hours. The result of X-ray diffraction showed that the strongest peak intensity of sample decrease when available strontium ions doping. The crystallite size decreased from 23.50 to 22.65 nm while the strain increased. The IR spectra of the sample with strontium doping have lower transmittance than the sample without doping. The FTIR result showed that the strontium ions were suppressing the ions in the octahedral site. The magnetic properties showed that coercive field increased and the saturation magnetization decreased with the addition of strontium ions in cobalt ferrite nanoparticles.
