Ni doped ZnO thin films for diluted magnetic semiconductor materials
Ni doped ZnO (Zn1 xNixO) thin films were grown on quartz substrates via magnetron sputtering deposition process with the Ni concentrations of 5, 10 and 20 at.% in the films. The effects of Ni doping level and post annealing on the structural and magnetic properties of Zn1 xNixO films were investigated by means of X-ray diffraction (XRD), alternating gradient magnetometer (AGM) and photoluminesc...
متن کاملInsight into the Origin of Ferromagnetism in Fe-Doped ZnO Diluted Magnetic Semiconductor Nanocrystals: An EXFAS Study of Local Structure
In this paper we have studied Structural, local structural and magnetic properties of sol-gel derived Zn1-xFexO (0≤x≤0.06) nanoparticles. The crystalline structure and crystallite size have been estimated by X-ray diffraction with Rietveld refinement and high-resolution transmission electron microscopy (HRTEM). Other structural and local structural properties have been studied by Extended X-ray...
متن کاملMagnetic Properties of Fe and Ni Doped SnO2 Nanoparticles
In this work, we report the room temperature ferromagnetism in Sn1‐xFexO2 and Sn1‐xNixO2 (x = 0.00, 0.03 and 0.05) nano‐crystalline powders. All the samples were prepared using co‐precipitation method. X‐Ray Diffraction (XRD), transmission electron microscopy (TEM), energy dispersive x‐ray analysis (EDAX), UV‐ visible absorption spectroscopy and room temperature magnetiz...
متن کاملSynthesis of Fe-doped CeO2 Nanoparticles Prepared by Solgel Method
Nanomaterials have achieved remarkable technological advances in bulk materials due to their excellent physical, chemical and biological properties. cerium oxide (CeO2) nanostructured doped with Fe ions is attractive due to improvement in redox properties, transport property and surface-to-volume ratio. In this research, Fe-doped CeO2 nanoparticles (NPs) were prepared by s...
متن کاملTheory of diluted magnetic semiconductor ferromagnetism
We present a theory of carrier-induced ferromagnetism in diluted magnetic semiconductors ( III1-xMnxV) which allows for arbitrary itinerant-carrier spin polarization and dynamic correlations. Both ingredients are essential in identifying the system's elementary excitations and describing their properties. We find a branch of collective modes, in addition to the spin waves and Stoner continuum w...
