Room temperature ferromagnetism in Ni doped In2O3 nanoparticles

In the present work, Ni doped In2O3 nanoparticles were prepared using simple co-precipitation method. From the x-ray diffraction analysis it is observed that all samples exhibit single phase polycrystalline nature. All the diffraction lines correspond to the bixbyite type cubic structure. A UV visib...

Description
Summary:In the present work, Ni doped In2O3 nanoparticles were prepared using simple co-precipitation method. From the x-ray diffraction analysis it is observed that all samples exhibit single phase polycrystalline nature. All the diffraction lines correspond to the bixbyite type cubic structure. A UV visible analysis reveals that optical band gap decreases from 4.63 to 3.84eV with Ni doping. DC magnetization measurements reveal that Ni doped In2O3 nanoparticles exhibit room temperature ferromagnetism.
