The magnetic properties of Gd doped ZnO nanowires

We present a study of the ferromagnetic properties of Gd doped ZnO nanowires (Nws) fabricated by means of a chemical vapor deposition process. The sample was grown with a Gd mole ratio 5% in a mixed Zn/Mn source under a constant O-2/Ar gas mixture flowing at 580 degrees C followed by annealing at 80
