abstract = "Zn100-xOFexsamples were obtained by mechanical alloying (MA) with different milling times. The purpose of this work was to analyze the variation of hyperfine parameters of the system with milling time. X-ray patterns show that pure ZnO under mechanical milling is not contaminated; additionally the system obtained by mechanical alloying has a wurtzite structure similar to pure ZnO. M{\'o}ssbauer spectra show that all samples present two phases: paramagnetic and ferromagnetic. The milling time contributes to increase the paramagnetic phase; however, the M{\'o}ssbauer spectra taken for samples milled during 36 and 99 hours indicates that there is a solubility limit for Fe atoms in ZnO lattice due that the spectra area remains nearly constant after 36 h. M{\'o}ssbauer spectrometry shows that the Fe atoms which penetrate inside the ZnO matrix behave like Fe3+and Fe2+. {\textcopyright} Springer Science+Business Media, LLC 2012.",
