Room Temperature Ferromagnetism of La doped ZnO Nanorods

V. Shally

Abstract: La-doped ZnO nanorods with different La concentrations (1 wt % and 5 wt %) were synthesized by novel wet chemical method and characterized by various sophisticated techniques such as XRD, UVDRS, FESEM, EDS and VSM. This method is simple, calcination temperatures are not required and nanorods are prepared by low temperature. The XRD patterns of the La-doped ZnO nanoparticles indicate hexagonal crystal structure with an average crystallite size of 49.44 and 35.83nm. The XRD analysis showed hexagonal structure. Field Emission Scanning Electron Microscopy (FESEM) result reveals that the La doped ZnO nanoparticles are rod like shape. EDS analysis shows the incorporation of La ions in the ZnO lattice. The band gap of the nanoparticles is determined from UV-DRS. Magnetic studies reveal the ferromagnetic behavior in La doped ZnO nanorods.
