Magnetic Properties of Ni-doped ZnO Nanocombs by CVD Approach
The search for above room temperature ferromagnetism in dilute magnetic semiconductors has been intense in recent year. Arrays of perpendicular ferromagnetic nanowire/rods have recently attracted considerable interest for their potential use in many areas of advanced nanotechnology. We report a simple low-temperature chemical vapor deposition (CVD) to create self-assembled comb-like Ni-/undoped...
متن کاملNi 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 کاملSynthesis and magnetic properties of Zr doped ZnO Nanoparticles
Zr doped ZnO nanoparticles are prepared by the sol-gel method with post-annealing. X-ray diffraction results show that all samples are the typical hexagonal wurtzite structure without any other new phase, as well as the Zr atoms have successfully entered into the ZnO lattices instead of forming other lattices. Magnetic measurements indicate that all the doping samples show room temperature ferr...
متن کاملSynthesis and magnetic properties of Mn doped ZnO nanowires
Mn doped ZnO nanowires have been synthesized using a simple autocombustion method. The as-synthesized Mn doped ZnO nanowires were characterized by X-ray diffraction and transmission electron microscopy. An increase in the hexagonal lattice parameters of ZnO is observed on increasing the Mn concentration. Optical absorption studies show an increment in the band gap with increasing Mn content, an...
متن کاملStructure and magnetic properties of Mn-doped ZnO thin films
We report the structure and magnetic properties of Zn1–xMnxO thin fi lms grown on Si(001) substrates by pulsed laser deposition. Structure and phase evolution with Mn doping has been studied using x-ray diffraction, electron diffraction, and high-resolution electron microscopy. The undoped and 1% Mn-doped ZnO fi lms are completely (001) oriented, and further Mn doping deteriorates the (001) ori...
