| Abstract | The results Co and Fe implanted ZnO thin films were studied before and after 200 MeV Ag ion irradiation. The as-implanted films shows the presence of nano sized Co and Fe clusters as seen through XRD patterns and exhibited high resistivity compared to un-implanted films. After Ag ion irradiation the Co and Fe clusters get dissolved in ZnO lattice and the films resistivity reduced to half of the as implanted values. The magnetic properties of Ag irradiated films were confirmed through magnetization hysteresis and Co implanted films exhibit higher magnetization compared to Fe implanted films. |
