چکیده

The modulation of the distribution of magnetic ions embedded in the host is crucial for the functionality of dilute magnetic semiconductors. Through an element-specific structural characterization, we observe the formation and enhancement of an unrevealed Co-doped ZnO phase and consequently magnetic properties from paramagnetism to ferromagnetism are controlled by surface-modification.

Synthesis and study of co-doped zinc oxide nanoparticles with copper, magnesium, calcium, and cobalt ions by microemulsion method

In the present study, zinc oxide nanoparticles were synthesized by simultaneous doping of Zn0.98Cu0.02O with Ca2+, Mg2+, and Co2+ ions using the microemulsion method. The phase, crystallization, and particle size of samples were identified by X-ray diffraction (XRD) analysis. The formation of the desired phase was confirmed by, X-ray diffraction. Also, the infrared spectrum (Far-FTIR) was confi...

Chemical manipulation of high-T(C) ferromagnetism in ZnO diluted magnetic semiconductors.

We report the use of targeted p- and n-type chemical perturbations to manipulate high-T(C) ferromagnetism in Mn(2+):ZnO and Co(2+):ZnO in predictable and reproducible ways. We demonstrate a clear correlation between nitrogen and high-T(C) ferromagnetism for Mn(2+):ZnO and an inverse correlation for Co(2+):ZnO, both as predicted by recent theoretical models. These chemical perturbations reveal r...
