Abstract

In this paper we report the results on the fabrication of diluted magnetic semiconductors Zn1−xMnxO1−ySy thin films with manganese x = 0.05 and sulfur 0 ≤ y ≤ 0.15 compositions, respectively, by using ultrasonic spray pyrolysis method. The influence of the sulfur concentration on the band gap energy, structural and magnetic properties have been studied by using optical transmission, X-ray diffraction and superconducting quantum interference device (SQUID) measurements, respectively. The morphology and composition of samples were studied by using Scanning Electron Microscope (SEM) and X-ray photoelectron spectroscopy (XPS). With increasing of the sulfur concentration the band gap energy of composition decreases, while the magnetization increases proportional to the sulfur concentration.
