Magnetic and Mssbauer effect studies of ZnO thin film implanted with iron ions to high fluence

Abstract

We present the results of magnetic and Mssbauer effect studies of zinc oxide thin film obtained by RF magnetron sputtering and implanted with 40 keV iron ions to a fluence of 1.5?1017 ion/cm2. As-implanted and post-annealed sample shows ferromagnetic properties at room temperature and consists of paramagnetic and ferromagnetic phases according to Mssbauer spectroscopy.
