Description |
The effect of oxygen vacancies on ferromagnetism (FM) in Zn(1-x)Mn(x)O thin films grown by radio frequency (RF) sputtering has been investigated. The grown films at different oxygen pressures have been characterized by X-ray diffraction (XRD), Hall effect, photoluminescence (PL) and vibrating sample magnetometry (VSM). The observed ferromagnetism/diamagnetism by the VSM measurement due to the variation of oxygen vacancies has been confirmed by XRD, PL, and Hall results. The vacancy-mediated FM has been explained by the formation of magnetic polarons. (C) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
