“…To synthesize Fe-doped ZnO nanoparticles, various methods were applied, such as chemical pyrophoric reaction [11], thermal decomposition of metal precursors [28], sol-gel [15], mechanical alloying [29] and plasma-assisted molecular-beam epitaxy [30] methods. In this work, we introduce a facile, inexpensive, effective, environmentally friendly and very fast way of producing Fe-doped ZnO powder by using a co-precipitation method that allows for easy incorporation of metal ions into the lattice and the adjustment of the particle size by applying subsequent high-energy ball milling [31] for various durations.…”

Iron-doped ZnO nanoparticles have been synthesized through high-energy ball milling of powders produced by the co-precipitation method. Fine particles with an average size down to 40 nm have been obtained after 15 min of milling. Fe(3+) cations have been incorporated into the ZnO lattice within the limits of the solubility. By using multi-frequency and high-field electron paramagnetic resonance (EPR) we have resolved all electronic transitions for the S = 5/2 high-spin system and have accurately determined the EPR spin-Hamiltonian parameters. By combining data from crystallographic x-ray diffraction and EPR with the semi-empirical Newman superposition model we have found the local configurational position of Fe(3+) and have confirmed the symmetry of the lattice. Results presented in this paper indicate that Fe cations most probably substitute at Zn-sites in ZnO. At nanosizes the effect of Fe(3+) cations on the surface becomes remarkable: additional size effects can be observed in the EPR spectrum, which are different from the spectrum of bulk.

“…ZnO doped with 3d transition metal (TM) elements have been studied widely since the calculation model by Dietl et al (2008) who have predicted the possibility of ferromagnetism in ZnO with a small amount of Mn as an impurity. Several magnetic, magnetooptical and magneto-transport properties were observed in ZnO systems doped by transition metals, including Mn-added ZnO (Fukumura et al 1999;Ando et al 2001;Jin et al 2001;Wi et al 2004;Piamba et al 2011;Iqbal et al 2011), Fe-added ZnO (Ueda et al 2001;Mok Cho et al 2002;Piamba et al 2011), Co-added ZnO (Ueda et al 2001;Lee et al 2002;Mok Cho et al 2002;Prellier et al 2003;Venkatesan et al 2004;Wi et al 2004) and Ni-added ZnO (Lee et al 2002;Prellier et al 2003;Ekicibil et al 2012).…”

Using ab initio calculations on Zn 0⋅975-x Fe 0⋅025 Cu x O (x = 0, 0⋅01, 0⋅02, 0⋅05), we study the variations of magnetic moments vs Cu concentration. The electronic structure is calculated by using the Korringa-Kohn-Rostoker (KKR) method combined with coherent potential approximation (CPA). We show that the total magnetic moment and magnetic moment of Fe increase on increasing Cu content. From the density of state (DOS) analysis, we show that Cu-induced impurity bands can assure, by two mechanisms, the enhancement of Fe magnetic moment in Zn 0⋅975-x Fe 0⋅025 Cu x O.

“…Nanostructures of Fe-doped ZnO (ZFN) can be obtained by many methods of synthesis [5,6], in this work we use the mechanical alloying, it is a simple and inexpensive method [7], these nanopowders of Fe-doped ZnO were obtained by mechanical milling [8] with different milling time (0 h, 3 h, 6 h, 24 h) in order to study their structural and microstructural properties using the X-ray diffraction (XRD) and the vibrating sample magnetometer (VSM) to examine the magnetic property, It has been shown that the distribution and the local environment of the dopant have significant effect on the magnetic structure. This technique can be used to study the magnetic properties and state of the doped Fe in ZnO.…”

In this work we study the ZnO powder nanoparticles mechanically alloyed doped with iron to investigate the structural, microstructural and magnetic properties using X‐ray diffraction (XRD) and Vibrating Sample Magnetometer (VSM). The ZnO starting pure powder exhibited a hexagonal crystal structure with space group P63mc of ZnO, however, with the introduction of 1% Fe in the ZnO milled powder, the hexagonal ZnO phase remained unchanged, whereas the microstructural parameters were subject to significant variations due to the introduction of Fe atoms into the ZnO hexagonal matrix to replace oxygen ones.
