Magnetic Properties of Fe Doped, Co Doped, and Fe+Co Co-Doped ZnO
The structural, electronic and magnetic properties of Zn0.95Co0.05O, Zn0.95Fe0.05O and Zn0.90Fe0.05Co0.05O nanoparticles prepared by a sol-gel method are presented and discussed. Xray diffraction and optical analysis indicated that high spin Co ions substitute for the Zn ions in tetrahedral sites. Fe Mössbauer spectroscopy showed the presence of isolated paramagnetic Fe ions in both Fe doped an...
متن کاملPreparation and Properties of Co-Doped ZnO Nanowires
Spintronics aims at developing a new generation of electronic materials for consumer products based on electron spin rather than on electron charge. Its main objective is the fabrication of new devices based on semiconductor materials with magnetic behavior (so called diluted magnetic semiconductors). These devices combine the manipulation of electrons as classically known in semiconductor devi...
متن کاملSonochemical synthesis of undoped and Co-doped ZnO nanostructures and investigation of optical and photocatalytic properties
In this paper, undopedZnO and Co-ZnOnano structureswith different molar ratio of Cobalt have been synthesized by the sonochemical method. Structure have been characterized by Fourier Transform (FTIR) and UV–Vis spectroscopy,Scanning Electron Microscopy (SEM), Energy Dispersive Analytical X-Ray (EDAX), and X-Ray Diffraction (XRD) methods. Moreover, the direct band gap has been calculated by Tauc...

متن کاملStructural, chemical and magnetic properties of secondary phases in Co-doped ZnO
We have utilized a comprehensive set of experimental techniques such as transmission electron microscopy (TEM) and synchrotron-based x-ray absorption spectroscopy (XAS) and the respective x-ray linear dichroism and x-ray magnetic circular dichroism to characterize the correlation of structural, chemical and magnetic properties of Co-doped ZnO samples. It can be established on a quantitative bas...
