Room temperature Ferromagnetism in Th1-xFexO2-d (x = 0.0, 0.05, 0.10, 0.15, 0.20 and 0.25) nanoparticles
O. D. Jayakumar, I. K. Gopalakrishnan, A. Vinu +2
Nanocrystalline (Th1-xFex)O2-d particles with different Fe concentrations (x = 0.0, 0.05, 0.10, 0.15, 0.20 and 0.25) have been prepared by a gel combustion method. Rietveld refinem…
Significant enhancement of room temperature ferromagnetism in surfactant coated polycrystalline Mn doped ZnO particles
O. D. Jayakumar, I. K. Gopalakrishnan, C. Sudakar +2
We report a surfactant assisted synthesis of Mn doped ZnO polycrystalline samples showing robust room temperature ferromagnetism as characterized by X-ray diffraction analysis, Tra…
Magnetic properties of Hydrogenated Li and Co doped ZnO nanoparticles
O. D. Jayakumar, I. K. Gopalakrishnan, K. Shasikala +1
The effect of hydrogenation on magnetic properties of Zn0.85Co0.05Li0.10O nanoparticles is presented. It was found that the sample hydrided at room temperature (RT) showed weak fer…
