Nanosized powder of ZnO doped with 5 at% of Fe was prepared and characterized by X ray diffractometry, while local atomic arrangements around different absorbing atoms was characterized by EXAFS measurements. Also, existence of significant magnetic moments of absorbant atoms was investigated using XMCD technique, while overall magnetic properties were sampled by magnetometric measurements. To get better insight in mechanisms behind such a subtle effect, ab initio calculations of electronic structure of dopped system has also been performed. Although, calculations predict small magnetic moments on Fe and to small extent on neighbouring atoms, XMCD and magnetic measurements reveal no sign of magnetic ordering in this compound, proving once more the decisive role of preparation technique in obtaining the desired effect.
