Abstract
In the present work, we have prepared Co doped In2O3 nanoparticles using co-precipitation method. The prepared nanoparticles were characterized by the X-ray diffrraction, scanning electron microscopy and dc magnetization hysteresis loop measurements. From the X-ray diffraction analysis it observed that all sample exhibits single phase polycrystalline nature. All the diffrraction lines correspond to the bixbyite cubic structure. The full width half maximum (FWHM) calculated from XRD pattern has been found to decrease with increase in the Co contents, indicating that particle size decreases with increase in the Co concentration. FE - SEM micrograph reflects the nanocrystalline behavior of all the samples and shows that doping of Co ions hinders growth of the particles. DC magnetization measurements reveal that Co-doped In2O3 samples exhibits room temperature ferromagnetism.
