Dussan, S. and Singh, M. K. and Kumar, A. and Katiyar, R. S.. (2011) Synthesis, Structural and Magnetic Properties of Ni-Doped In(2)O(3) Nanoparticles. Integrated Ferroelectrics, 125. pp. 155-161. ISSN 1058-4587Full text not available from this repository.
Pure and Ni-doped In(2-x)Ni(x)O(3) (x = 0.0, 0.01, 0.05, 0.1) nanocrystalline powders were synthesized using sol-gel process. The XRD patterns revealed the formation of nanocrystalline particles with cubic bixbyte crystal structure. The average crystal size was calculated from XRD patterns using Debye-Scherer's Equation for (222) peak and it was found to be 8 nm. This observation agrees well with the particle size estimated from the transmission electron microscope (TEM). The observed Raman peaks in the doped materials were negligibly shifted towards the lower frequency. This clearly indicates that Ni ions are incorporate into the host In(2)O(3) structure, in agreement with the XPS measurements. The Raman spectra show that the nanoparticles are free of secondary crystalline phase. The temperature dependent magnetization showed no evidence of ferromagnetism at room temperature.
