We report the room temperature ferromagnetism in Ag doped ZnO films grown by RF magnetron sputtering. X-ray diffraction of undoped and 2% Ag doped ZnO show the hexagonal wurtzite structure corresponding to c-axis (002) orientation. The presence of defects within Ag-doped ZnO films can be revealed by electron paramagnetic resonance. It has been observed that saturated magnetic moment increase as we increase the oxygen vacancies during deposition.
