Impurity Effect on Magnetic Properties in Pure and TM-Doped Nanophase-SnO2 Synthesized by Facile Co-Precipitation Method
Abstract: Samples of ferromagnetic Sn1-xFex O2 (x=0, 0.2, 0.4, 0.6 and 0.8) nanoparticles were prepared by a facile co-precipitation method using stannic chloride pentahydrate and ferric chloride tetrahydrate. Magnetic properties were studied using vibrating sample magnetometer. It was observed that impurity controls the magnetic properties significantly. The magnetic coercive field ranged from 142.122Oe to 1622.674Oe, mostly increasing with doping concentration, and maximizing at a concentration of 6% of Fe. The retentivity increased 10-17 times, and saturation magnetization 2-6 times, by controlling doping concentration. It is the finding of the experiment that at a dilute impurity of 2%, the sample shows the maximum retentivity with saturation magnetization, and a coercive field of 216.36 Oe.
