Abstract

Abstract The effect of oxygen vacancies on ferromagnetism (FM) in Zn_1−xMn_xO 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.
