“…These M -H curves can be regarded as an element and orbital specific magnetization measurement for the Gd 4f , Ni 3d, and Ce 4f electrons. The Gd M 5 and Ni L 3 XMCD signals show similar behaviors that the XMCD intensity increases with magnetic field, and almost saturates at around 2 T, although the Ni L 3 XMCD signal slightly decreases with an increase of magnetic field above 2 T. The M -H curve of Gd 4f electrons, which have a dominant magnetic contribution in this system, is consistent with the result of magnetization measurement along the same axis [16]. The most remarkable finding here is that the Ce M 4 XMCD intensity linearly decreases with an increase of magnetic field after taking a maximum at around 2 T. The result implies the possibility that the Ce 4f total magnetic moment, which at first aligns antiparallel to the direction of magnetic field, may turn into the opposite direction under sufficiently large magnetic field above 10 T. This behavior can be interpreted as a precursor of spin flip.…”

The magnetic properties of Ce 0.5 Gd 0.5 Ni was studied by soft X-ray magnetic circular dichroism (XMCD) study at the Gd M 4,5 , Ni L 2,3 , and Ce M 4,5 absorption edges, which gives information about the magnetic moments of the Gd 4f , Ni 3d, and Ce 4f electrons. It was found that, while the magnetic properties of this material are dominated by the ferromagnetic behavior of the Gd 4f electrons, the Ni 3d and Ce 4f electrons have finite magnetic moments aligned antiparallel to the Gd 4f magnetic moment. Although the Gd 4f and Ni 3d magnetic moments show a saturation at around 2 T, the Ce 4f magnetic moment takes a maximum at around 2 T and then shows a linear decrease with magnetic field.

“…May be there are also some isolated Mn atoms which are paramagnetic in nature and that increases the paramagnetic contribution for increasing concentration. Similar behavior and magnetization values for Mn-doped ZnO for comparable concentration have been reported in the literature [32,34,35]. On the other hand, the coercive field decreases with increasing concentration (Fig.…”

“…We noticed that the crystallite size decreases with increasing Mn doping. This behavior is explained by the formation of defects during the sol-gel method process and has been reported previously [32,33]. This may be attributed to various factors: (1) Mn 2?…”

We report the synthesis of Zn 1-x Mn x O nanoparticles prepared by a sol-gel processing technique for x ranging from 0 to 0.05. The structural, morphological and magnetic properties of the nanoparticles were investigated by XRD, transmission electron microscopy and superconducting quantum interference device. The structural properties showed that the obtained nanoparticles are in wurtzite phase structure with the presence of ZnMnO 3 secondary phase at higher concentration. The crystallite size decreases with increasing Mn concentration and is in the range of 35-17 nm. All the samples are ferromagnetic with clear hysteresis loop at room temperature but with low values for the saturation. It was found that increasing Mn concentration is not helping the long range ferromagnetic order, which might be due to the antiferromagnetic exchanges. This ferromagnetism order is due mainly to the defects and to the substituting of Mn in the ZnO host rather than from the secondary phases of Mn.

“…(ii) The role of Mn oxide phases (below the detection limit of XRD) was eliminated, as none of these could be responsible for RT FM. Metallic Mn, MnO and MnO 2 are all AFM below the Neel temperature of 100 K, 116 K and 84 K respectively and Mn 3 O 4 is ferromagnetic with Currie temperature $45 K. 37,42,43 In order to probe the local atomic structure and occupation sites of Mn ions in ZnO, XAS of few selected lms were performed.

Correlation between magnetic and micro-structural properties of low energy ion irradiated and un-irradiated Zn_0.95Mn_0.05O films

To establish intrinsic ferromagnetism (FM) and to detect its micro-structural origin (if any), sol-gel derived Zn 0.95 Mn 0.05 O films have been undergone low energy (800 keV) Ar 4+ ion irradiation. The structural, optical, magnetic and micro-structural properties of irradiated and un-irradiated films were investigated by X-ray diffraction (XRD), UV-visible and photoluminescence (PL) spectroscopy, field and temperature dependent magnetization measurements, X-ray absorption near edge spectroscopy (XANES) and extended X-ray absorption fine structure (EXAFS) spectroscopy. All the films exhibit single-phase wurtzite structure and intrinsic FM. The band gap and band tail parameters show systematic variation with fluence of irradiation.PL spectra exhibit a green emission peak (oxygen vacancy) and that has been suppressed significantly for
